i salvaged a 1.6kw motor from a vacuum cleaner-wishing to make it into a blower but i want to use the impeller as a propeller- i can do this by changing the running direction of the motor
however i do not know how to do this-there are two wires leading to the motor brown and blue these wires are also connected to a capacitor in Parallel they lead straight from the plug
i have tried disconnecting the capacitor to see if i can hand start the motor in the opposite direction-however even when the capacitor is disconnected the motor still runs in the same direction
there are no more wires coming out of the motor and the 2 brushes are connected to the field wires(the electromagnets around the armature)- can the direction of the motor be changedHow would you change the running direction of a Universal motor running on AC?Universal motors are usually series connected, meaning the armature and field are in series. You have to reverse the connections ro one of them, the armature or the field.
The wiring will look like supply active, field in, field out, brush in (to armature), brush out, supply return. The capacitor is a electrical noise suppressor, just connected across the supply, or sometimes across the brushes.
If it is shunt wound as you seem to describe (meaning the field is across the supply and so is the armature) then the solution is still the same, reverse one of them.

Man's greatest invention hand's down no question!?
As we near the end of the first month of the new millennium, I have begun to ponder many things that until now have been taken for granted. As explosions of thought permeate my cerebrum, I find that I just must write! Anyway, here we are in the Year of our Lord, 2000, and computers and the Internet seem to be taking over the world. Everybody everywhere is trying to sell us something. We have: e-bays, e-commerce, e-links, e-mags, e-mails, e-malls, e-quests, and even e-zines! The old saying used to be, %26quot;The Ayes have it!%26quot; Now, it seems that the E檚 have it.
GIMME AN %26quot;E%26quot; !!!
At the risk of sounding stupid, I guess the E stands for electronic, huh? So naturally, many, if not most of you, would quickly answer the question posed in my title by saying, %26quot;that檚 easy . . . the computer is man檚 greatest invention.%26quot; Right? . . . WRONG !!! %26quot;How so?%26quot; You may ask. Well, inside just about every computer, there exists a little device whose function is to %26quot;cool%26quot; it; otherwise, it would over-heat and %26quot;CRASH!%26quot; Then where would we all be, if all the computers in the world simply could not function?
%26quot;Oh, abacus, abacus, wherefore art thou, abacus?%26quot;
Next, consider all the buildings in the world, both residential and commercial. What if all the furnaces, boilers, fans, and air conditioners simply could not work because of the absence of this same device? We would certainly be very uncomfortable most of the time, correct? Our entire environment would be drastically changed for the worse.
What if all the: automobiles, trucks, planes, trains, boats and ships would not work, for lack of this device? Transportation of people, products, and services would cease and desist! It would be kind of difficult, to say the least, for you to even acquire that %26quot;almighty%26quot; computer, wouldn檛 it? And even if you foot-peddled your little tri-cycle somewhere and back to haul your little e-Wonder home, guess what? It would still over-heat and CRASH! Oh, yes, lest I be remiss, let us not forget all the: washing machines, driers, refrigerators, freezers, turn-tables, printers, fax machines, blenders, power tools, and every other mother-lovin?appliance on the earth . . . none of them would work either!
By now you have gotten the picture, and know this %26quot;mad-man檚%26quot; answer, right? Is it: a micro-chip, a transistor, a diode, a capacitor, a voltage regulator, a generator, an alternator, or some other Electronic thing-a-ma-gig? NOPE! In my old 1953 edition of Webster檚 New World Dictionary of The American Language, on page 961, it is defined as follows:
motor - n. 1. anything that produces or imparts motion. 2. an engine; especially, an internal-combustion engine for propelling a vehicle. 3. a vehicle propelled by an engine; especially, a motorcar; automobile. 4. in electricity, a machine for converting electrical energy into mechanical energy.
So, there you have it, my contention is that the lowly motor is man檚 greatest invention, merely because it has such a wide-spread influence over just about every other machine that was ever invented.. Practically every vehicle, ever manufactured anywhere needs a %26quot;starter motor%26quot; to engage the engine, in order to overcome inertia, whether it is internal combustion, gasoline powered, diesel powered, or even turbine powered. Every cooling or heating device which utilizes a fan, whether a propeller, or impeller, needs a motor to turn the shaft which spins the fan. While the greater majority of heating systems may be forced hot air, and utilize such a fan motor, even older homes like our 65-year-old hot water radiator system must have a circulating pump to force the hot water throughout the house. This pump is powered by an electric motor.
Q.E.D. : No motor = no motion . . .
No motion = no nuttin?= Nuttin?Honey!
As the sun sets in the west, and I bid you adieu, a startling revelation comes to mind. Namely, just what powers these great gadgets we call motors? Er, ah, well, um, you see, I guess it would be . . . electricity, huh?
Now we all know the story of the great inventor, Benjamin Franklin and his kite experiment, correct? Well, suffice it to say that he did not invent electricity, he just discovered it. So, while we may not know exactly who invented the greatest invention of man-kind, the motor (or so I say), maybe we can still give Ben three %26quot;thumbs?up%26quot; and a %26quot;double jiggle%26quot; for his efforts, because without electricity, we檇 be in a real peck of trouble. But that檚 another story, for another day!Man's greatest invention hand's down no question!?The wheel was probably the greatest invention. No wheel, no motor.

I daresay that had indoor plumbing never been invented, the world would be a much less pleasant place to be.
If you've never experienced not having running water, and don't know what an %26quot;outhouse%26quot; is, you're simply unqualified to rank anything else as the most important invention. If the astronauts that went to the Moon ever said they missed anything more, I'd call them liars.

Where does the power increase come from by increasing frequency from 50 to 60hz?
http://www.engineeringtoolbox.com/affinity-laws-d_408.html
in this link we can see on the graph that the increase in speed of a pump's impeller causes the pump to 'push' a liquid with more power at a higher pressure..
now when you change the current frequency of a pump from 50 to 60 the speed increases by 20% so this would mean according to the graph that the pump will push with more power..this means that this increase of power is coming from the motor driving the impeller...how does the increase in frequency cause an increase in power consumption by the motor? does it make it pull more current from its ource or a higher voltage? i know power=lVcos0(frequency is not in the formula)..Where does the power increase come from by increasing frequency from 50 to 60hz?Notwithstanding the rambling and rather academic dissertation by HASD, who seems not to have read the question, the situation is quite simple.
Assuming, as would often (but not always) be the case, that a motor can still operate normally and safely at the higher speed (60 Hz), then it would react fully automatically to any increase in its torque (as applied by the load) by simply drawing more current from its supply. As you correctly remark, frequency doesn't come into it. What the frequency basically does is determine the speed.
A motor itself is not able to alter the voltage with which it is supplied so its reaction is confined to drawing more current as its torque increases. It is the user who has to provide a suitable voltage for the motor and although most motors might work well at 60Hz on the same voltage as at 50, the ideal voltage would usually be higher by about 20%. If the user makes some or all of the voltage change, then the current change demanded by the motor will be correspondingly less.
I take the opportunity to recommend Alfonso to go back to school for while! There's an awful lot about electricity that he hasn't grasped very well. Meanwhile humanity would be better served by his silence.Where does the power increase come from by increasing frequency from 50 to 60hz?Uh.... No.
20% increase, must be living in dreamland. the example shows a 10% increase, and there's nothing in that link about increasing frequency.
If the frequency goes up to 60HZ it also means an increase in power being supplied to the motor, because the electricity is arriving more rapidly than before.
The power is averaged out instead of using peak voltage,so if power comes in more rapidly the averages will be higher.It's higher because less time is spent at zero and the peaks are coming in more frequently. it's kinda hard to show this without an example if a sine wave.
AN increase in power speeds up the motors turning rate, which gives more horsepower (voltage and current rates are moot points, they are both higher).Where does the power increase come from by increasing frequency from 50 to 60hz?The link you posted only seems to mention the obvious, namely the faster you turn the pump, the more power that must be used.
Now, what is NOT mentioned in the link is what is driving the pump. It could be a hand crank, a gasoline-powered engine, or an electric motor.
So... you seem to be interested in the case of driving the pump with an electric motor. Furthermore, you mention 50Hz vs 60Hz, which implies you are dealing with an AC system.
AC motors work by creating a rotating magnetic field in the stator. By switching from 50Hz to 60Hz, you are making this field turn faster.
If you use a synchronous AC motor (which is not common), then the motor MUST keep up with the rotating magnetic field (or the motor would quickly burn out).
On the other hand, it you use an AC induction motor (more common), the rotor is free to slip relative to the rotating magietic field, so (depending on the load), the switch from 50Hz to 60Hz may not change the speed much at all. If the load is very light then it will change by the 20% you mentioned.
An AC motor running at no-load is not really using much power at all even though it is spinning rapidly. As the load is increased (as will occur in the case of your pump), then the induced magnetic field in the rotor slips relative to the rotating field of the stator. It is the phase difference between the two that defines how much power is consumed (ignoring the losses due to the resistive component of the motor coils and magnetic hysterisis).

I can't figure out how to drop the lower unit on a 1972 Mercury 1500(150HP) outboard. PLEASE PLEASE help!?
1)Do I have to disconnect any transmission cable or anything by the motor? If so, how?
2) How many bolts to I unscrew from the lower unit near the propeller?
3) Is there anything else that I should know?
Reason for dropping the lower unit is because I just bought this boat and I'm changing all the fluids, spark plugs, and water impeller. And by any chance you know what water impeller I need will help me too since I can't find it in the owners manual.
Thank you allI can't figure out how to drop the lower unit on a 1972 Mercury 1500(150HP) outboard. PLEASE PLEASE help!?Above post describes how to remove.
When replacing the lower, the shift shaft (Splined shaft in front of main shaft) must be put back the way it came off otherwise you can have a shift problem.
Put the throttle lever in neutral, turn the splined shaft on the lower so it is in the middle of it`s range (the prop must turn free so not in fw or rev gear) and the splines should align ok just before placing the lower back up. Dont forget the quad shaped O ring on the oil passage between the two halves!
Refill the oil from bottom up till it floods out the vent plug and use new seal washers.
FrankI can't figure out how to drop the lower unit on a 1972 Mercury 1500(150HP) outboard. PLEASE PLEASE help!?you can view your parts catalogue and engine schematic diagrams online at http://www.ishopmarine.com
the shift rod has to be disconnected. not sure where it is on that motor. on most engines of that size %26amp; vintage, it's under the bottom carburetor.
four retaining bolts, there might one more above the propeller, and there might even be one hidden under the torque tab. Score a line across it so you can get it back like it was.
put anti-sieze or similar on the retaining bolts when you reinstall, to prevent them getting froze up on there for next time. I use OMC gasket sealing compound.
put molly lube on the drive shaft splines, same reason.I can't figure out how to drop the lower unit on a 1972 Mercury 1500(150HP) outboard. PLEASE PLEASE help!?No need to panic,it's really not that hard.
1)Shift into forward gear.
2)There are 7 bolts to remove.First remove your trim tab.
There is a plug on the top of the drive unit and when you pop it out,down inside there is either a 5/16 or 3/8 Allen head bolt.
3)After you have removed it look up under the trim tab and you will see another Allen bolt.Remove it next.
4)On the underside just back a little from the last bolt there are 2 5/8 nuts to remove.
5)At the rear you will see two more 5/8 nuts to remove.After removing these there is one more back a little farther just up a little.Once you have removed the last nut it is ready to come off.It may be stuck on a little,so the easiest way to make it drop is to use a screw driver and pry down on the 2 nuts on the rear as you will have noticed that they would not come off all the way yet.The part number for your Impeller is 47-89984.

Questions about using Sand as Substrate in my Fish tank...?
I have a Jack Dempsey cichlid and if you know anything about them you know they like to dig. Right now I have regular colored gravel in my tank but I want to change it out and replace it with sand.
Here is the problem, I was given some gravel/sand mixed substrate but I had to change it out because the sand kept jamming up my impeller in my emperor hang on back filters.Is there a larger,heavier type sand that wont suck up into my filters I can use?How do you keep sand clean? Are you supposed to vacuum sand like you do gravel?
Here are my questions:
1. What is the best kind of sand can I buy that wont make my HOB filter stop constantly?
2. Where can I buy it?
3. Can you have snails in your tank if your substrate is stickily sand?(will it harm them?)
4. Will I lose all my beneficial bacteria if I change my gravel to sand?
Any help or advice would be great.I think sand looks better and I would like my JD to be able to dig without getting his face all jacked up.
Thanks folksQuestions about using Sand as Substrate in my Fish tank...?1 - Pool filter sand
2 - A pool supply store. It's cheap.
3 - They'll be fine with the sand. Whether they'll be fine with the Dempsey may be a bit different...
4 - You'll loose a good number of them. If you want, bag a bunch of it in a nylon stocking, and leave it in the tank for a while. Putting a small pump or powerhead blowing through it will help, too. But really, you should be able to switch it out without too much of a problem. Just monitor ammonia, just in case, and be prepared to intervene with water changes.Questions about using Sand as Substrate in my Fish tank...?Sand is not a good idea unless you have fish that stay on the top of the water, and even then, it is liely to get in your filter. Also, if you have cichlids that dig, and more than half of them do, they will get neurotic trying to constantly clear their territorial areas of sand, or just give up and become maladjusted.
Snails can adjust to sand. there are far more snails in the ocean than in fish tanks.
As far as your bacteria are concered, I would put some of the sand inside a stocking mesh securely tied at the top and leave it there until your tank recycles.Questions about using Sand as Substrate in my Fish tank...?I tried to help below but this will help more than I could: http://www.cichlid-forum.com/articles/sa
1. Try to find large grain sands. The grains aren't as easily carried away by current. Bigger than play sand size is what I look for.
2. I live in minnesota and there's stores around like home depot.
3. Snails are fine on sand. You can sometimes see grains stick to their slime trail.
4. I have read that changing substrate can send a tank into cycle stage again. Some people say they avoid this by slowing changing the substrate, one side or part of the tank at a time and then wait and repeat.
*Maintenance on sand is hovering over the sand to collect debri and poo. Once in awhile the sand should be %26quot;turned%26quot; to prevent nasty pockets of gas. Debris starts to decay in anaerobic conditions beneath the sand and it can stink. It's said to be toxic to fish if it builds up.
ps - Dempsey's are found in areas where sand is...http://en.wikipedia.org/wiki/Jack_Dempse

1. Try to find large grain sands. The grains aren't as easily carried away by current. Bigger than play sand size is what I look for.
2. I live in minnesota and there's stores around like home depot.
3. Snails are fine on sand. You can sometimes see grains stick to their slime trail.
4. I have read that changing substrate can send a tank into cycle stage again. Some people say they avoid this by slowing changing the substrate, one side or part of the tank at a time and then wait and repeat.
*Maintenance on sand is hovering over the sand to collect debri and poo. Once in awhile the sand should be %26quot;turned%26quot; to prevent nasty pockets of gas. Debris starts to decay in anaerobic conditions beneath the sand and it can stink. It's said to be toxic to fish if it builds up.
ps - Dempsey's are found in areas where sand is...http://en.wikipedia.org/wiki/Jack_Dempse
How to bleed a 1997 ford taurus cooling system?
ok i just changed the water pump on my 1997 ford taurus the water pump impellers were completely rusted away and we filled the system with water so we could flush everything out of the system and we cant seem to find a bleeder screw anywhere on the engine also there is no way to fit up the radiator seperatly we have to dump everything in the coolant recovery tank we jacked up the front of the car and started it but we are still afraid of air bubbles in the system.How to bleed a 1997 ford taurus cooling system?that is a self bleeding system. after draining the radiator and closeing back up just put in a gal of pure antifreeze and then a gal of water do it slow then start the car and turn on the heat all the way up and finish up with pure antifreeze, as it burps itself it will let any extra out the cap. that car is designed that way.How to bleed a 1997 ford taurus cooling system?there's usually 5 bleeder screws:
2 on the left side of the block, near the bottom
2 on the right side of the block, also near the bottom
1 on the radiator, on the bottom usually on the right side.
Don't worry about bubbles and make sure to run the engine once you have it filled with the water to engage the cleaning process. Make sure you use Prestone Cooling System cleaner or a similar product!

How would you change the running direction of a Universal motor running on AC?
i salvaged a 1.6kw motor from a vacuum cleaner-wishing to make it into a blower but i want to use the impeller as a propeller, i can do this by changing the running direction of the motor.
however i do not know how to do this-there are two wires leading to the motor brown and blue these wires are also connected to a capacitor in Parallel they lead straight from the plug.
i have tried disconnecting the capacitor to see if i can hand start the motor in the opposite direction-however even when the capacitor is disconnected the motor still runs in the same direction
there are no more wires coming out of the motor and the 2 brushes are connected to the field wires(the electromagnets around the armature)- can the direction of the motor be changedHow would you change the running direction of a Universal motor running on AC?You would need to reverse the direction of the current through the armature windings relative to the direction of flow through the field windings. The easiest way would be to swap the two wires going to the brushes, but I'd bet that they won't reach without extending them somehow.
There may be mechanical difficulties though. For example the impeller might be screwed on to the end of the motor shaft with the thing designed so that the screw tightens when the motor rotates in the designed direction, but will loosen itself going the wrong way.
I wouldn't operate it without the capacitor, it sounds like a spark/ interference suppressor.
Please be careful. It sounds like a machine with the capability to do you a fair bit of damage one way or another.How would you change the running direction of a Universal motor running on AC?Only by reversing the direction the current runs to the field windings relative to the armature. Reversible universal motors are commonly used on ac powered toy trains, most famously those by Lionel.
This may be a fools errand: I do not see that reversing the direction of rotation of the impeller is going to accomplish what you want to do: Most impellers are unidirectional, they work poorly, if at all, when rotated in the wrong direction. You should instead concentrate on how to arrange the duct-work so that the impeller moves the air as you desire in its present configuration.How would you change the running direction of a Universal motor running on AC?To chsangr yhe direction of your motor,just interchange connection of your blue wire from capacitor terminal to its common junctioneye make up emo style kid sweating

1968 Model Mercury 6 Horse Outboard Boat Engine?
I recently aquired an old jon boat and engine. How do I drop the lower unit on a Mercury 6 horse to change the water pump impeller?1968 Model Mercury 6 Horse Outboard Boat Engine?there will be several nuts a few inches about the prop the case will split there allowing you to access the impellor housing. however be carefull not to pull the water tube loose from the head or you'll be taking it apart at the upper end of the lower unit to get the tube back into place
Took hour to start boat and had many problems and would like some help.. thanks?
First ill start off that i have a 1974 evinrude 115 hp motor. 4 cylinder. motor sat for 3 years. i have changed the fluids and also changed the impeller. cleaned out the carbs and the fuel lines going to the carbs but not the line from tank to filter.
got to the boat ramp and i started in garage several times with no problem and then once i got to the boat ramp it did not want to start.. ran the battery down and hand to us jumper cables to recharge the battery from my truck. when we tried to start it i don't know how but the butterfly on the lower carb was a little open and i screwed around changing things up and once i got it closed it would flood it self. we would open the carb and fuel would flow out. i thought maybe the fuel lines were clogged but we got it started after an hour and once on the water i would have it opened up good then it would slow down and then hammer back into again by it self. i want to take my girlfriend out in it for her birthday in a few weeks and i dont want to have to paddle back to ramp.. when i tuned the carbs i did not find an adjustment screw so i adjusted them with the linkage on the side that opened and closed the butterflies. thanks for any help to come.Took hour to start boat and had many problems and would like some help.. thanks?The reason you couldn't find an adjustment screw on the carbs is because they have fixed jets -- no adjustment necessary.
erratic throttle response could be due to out of sync throttle valves, bad fuel quality, or intermittent ignition fault.
get some fresh gas in there (87 octane) mixed 50:1 with TCW3 certified oil. I'd just go ahead %26amp; replace the fuel line and primer bulb, just on general principle.
Do yourself a favor and use the champion spark plugs, surface gap UL77V.
Spark should jump a 7/16%26quot; gap on an inline tester clipped to the engine block. That'll indicate strong enough ignition to consistently produce a spark under heat %26amp; compression in the combustion chamber.
Compression should be upwards of 90 on that motor, and the lowest should be within 5 or 7% of the highest.
fuel flowing out the front of the carb means that your float valves are shot and need replacing.
order a couple carb kits from iboats.com and do the carbs right -- soak the metal parts overnight in carb cleaner, blow through all the passages with compressed air (or aerosol carb cleaner).
You probably know this already -- if you're talkin bout the butterflies at the front of the carb throats, those are choke valves -- the throttles are at the back (two per carb). Adjust the roll pin clip screws to where the throttles are closed at idle (idle speed setting is done entirely with spark advance).
Here's the basics of link %26amp; sync from memory -- you'd need a manual for the step-by-step but this should get ya close. Must be done in order:
Note: if you adjusted the length of the throttle lever linkage (attached to throttle cam yoke), you're screwed -- it has to be a precise length and you'll need the service manual for your specific engine for that measurement.
1. Find the idle set screw (starboard side of the powerhead in a spring-loaded nut -- the throttle lever rests against it at idle) -- idle speed should be about 650-700 in gear in the water, so set it to about 950 in neutral on the muffs then fine tune after launching. The idle set screw shouldn't be fully in or fully out -- if it is, use the thottle cable trunion nut (black thumb-wheel-looking thing) to adjust the cable length.
2. Set the roller on the upper carb to where the throttle cam makes contact with it right at the mark embossed on the cam.
3 Find the WOT stop screw in a spring-loaded nut on the starboard side; set it to stop the throttle lever when the throttle butterflies are horizontal.

Sounds like a carb float/needle valve sticking through lack of use.Took hour to start boat and had many problems and would like some help.. thanks?First and cheapest investment will be in a quality workshop manual. This will explain the exact set up for the carbies and how to correctly tune it. There are traps for the unwary when tuning the ignition systems on some of these older engines - testing in the wrong way may actually do more harm than good.
Those engines were pretty good for the time and have a good reputation in general - but even though the engine is 35 years old now your main problem will be the length of time it has sat. No two stroke will be happy with that - and at the very least you may have to rebuild the carbies, check all the fuel tubing for splits or pin-holes and make sure the ignition system is firing strongly.
Water pump impeller will possibly be getting pretty sad now too. If you have started it without any water to the leg it will be stuffed for sure.

How to disconnect 50 hp mariner outboard lower unit shift linkage ?
1993 mariner outboard need to change the water impeller, i loosened the bolts to drop the lower unit, but can't figure out where to disconnect the shift linkage. not getting any play in the lower unit housing either, should i try to break loose with a mallet? it has probably never been done.How to disconnect 50 hp mariner outboard lower unit shift linkage ?There is usually a hidden bolt either under the steering zinc or hidden behind a rubber cap. This is the most common error in trying to remove a lower unit. Once you find this last bolt, the unit should pull straight out.

Mercury 9.9 2 stroke 2001 Cooling system
Hi Guys
Does the mercury 9.9 2 stroke from 2001 have a cooling jet stream coming off the back? If not, then how is a good way the know if I need to have the impeller changed?
Thanks Guys
Mercury 9.9 2 stroke 2001 Cooling system=no water stream coming out means the water pump is out==Mercury 9.9 2 stroke 2001 Cooling systemOk...
So, I was told that this engine is supose to have a thermostat that only in case of overheating opens and shoots water of the back. Other than that the cooling fluid (lake water) is explelled thru the the same duct as the exaust (smoke) underwater.
the engine hasn't siezed yet. =)

I have a 40 hp mercury boat motor runs great but running a little too hot Ive changed the impeller already?
Ive changed the water impeller and housing, compression on all cylinders are 90psi . the motor doesnt seem to come out of the hole and plain out like it should, but it is running great. the water coming out of the outlet is pretty hot though and I dont want to harm the motor. How can I cool this heat problem and get the boat to come out on plain like it used tooI have a 40 hp mercury boat motor runs great but running a little too hot Ive changed the impeller already?Is the tel-tale stream steady? Check the temp of the engine block and head. The temp of these componets is what matters. Does the engine run better before it warms up? If it doesnt then the temp is not effecting the running of the engine. The down on power problem could be related to something else. How are the plugs, is the fuel fresh? Is the prop in good shape, has the engine been sync and linked lately? Run the engine at 1000 rpms on a hose and pull the spark plug leads off at a time. Make sure all the cylinders make the engine drop in rpm. If not the engine is not running on all the cylinders.I have a 40 hp mercury boat motor runs great but running a little too hot Ive changed the impeller already?Did you check for blockage in water passages? The old impeller could have broken up and clogged something. Was the water-pump to engine transfer tube installed properly and was the grommets on both ends inspected or replaced ? Had some lizards climb into thru hub exhaust once and caused some problems. Timing also plays a part in engine temp. Have you flushed your engine lately ? How about the thermostat,if its got one, is it alright ? Same prop, have you hit something lately? More weight in the boat ? Lean fuel mixture. Is the bottom of your boat clean. Sinc and link ? I know I'm going to hear about this one, but use 89 octane instead of 87, because 89 has more detergents to keep carbs and tops of pistons clean and not so much to add to the problem. Water temp should be around 125degrees for that motor........Hey Boat tech, does this engine have a poppet valve and spring?...( Bingo Mercman !)....Octane is (derived )from (additives) now days. It's all (87). 89 has more detergent and it's already in there. You don't have to add anything. That's why they make aftermarket additives to begin with because people use 87. They think they are saving money. Figure the cost of additives compared to the extra cost of 89 and the inconvenience of not having to deal with it. And no, higher octane now days will not burn a hole in the piston or burn the valves, in a engineers point of veiw, meaning burn time. But excessive use of octane boosting additives over time will. And I know, that you know, that we know, that there wasn't enough information in the question to answer it properly, but sometimes thats what makes it fun .... Don't it give you a chuckle when you feel like a blubbering idiot answering some these incomplete questions? I do.I have a 40 hp mercury boat motor runs great but running a little too hot Ive changed the impeller already?Need to know what year or serial number. 2, 3 or 4 cyl. 2 stk or 4stk.

Hey Link, we need to know what 40 it is before the thermostat, and popet question can be answered, some had them some did not. Also, quit wasting you money on 89, there are no more detergents in it than the 87 or 91. Mercury Quick clean or Yamaha Ring free will keep the cylinders and carbs clean, of course the Mercury product is better.I have a 40 hp mercury boat motor runs great but running a little too hot Ive changed the impeller already?If this is a 2 stroke motor it could be a seal problem. If it is an older engine and has been setting around and not run in a while the engine seals will dry out letting air leak into the fuel air flow leaning out the fuel mixture which will causing heating and performance problems. The exhaust should be hot or your cooling system would not be working.

How do you change the water pump impeller on a Mariner 8 hp outboard motor?
I have separated the Mariner 8 hp lower unit from the upper unit , taken apart the water pump, replaced the impeller and pusher the lower unit up on to the upper unit. It guides on fine until the last inch. It feels like the drive shaft is not alligning with the engine drive acceptor socket. The shift linkage appears and feels to be in place. The exhaust down tube feels like it is lined up. I tried turning the prop to rotate the drive shaft but it wont go together that last inch. Can some one help ????How do you change the water pump impeller on a Mariner 8 hp outboard motor?you may have to put the lower unit in fwd gear so as you are pushing up you can move the prop and the drive shaft at the same time to aid in aligning the splines.How do you change the water pump impeller on a Mariner 8 hp outboard motor?Ensure the %26quot;male%26quot; notch is inline with the %26quot;female%26quot; notch?How do you change the water pump impeller on a Mariner 8 hp outboard motor?okay..listen up, first you need to make sure you have removed the internal rotation drive modulator from the outer expulsion shaft. once you have done that you can safely align the exterior drive acceptor socket. if you put too much torque on the alternating drive train adaptor, you will snap the linkage and possibly damage your fuel cell resistors.
thanks for letting me waste 30 seconds of your times cause I really have no clue. good luck, though...I would take it to a boat shop and have them do it.
might be your best betHow do you change the water pump impeller on a Mariner 8 hp outboard motor?G'Day Sailinguy,
I have done water pumps on a few different brands of outboard motors, not a Mariner though, but they are all basically the same. The first and most important thing to observe is the water tube is correctly mated to the power head or you will damage the motor through overheating. Make sure the gear shift is in a position that makes the linkage at it's lowest point in the leg, so that it can be connected and tightened later. Ensure the gear box is in the matching position, this is usually in the forward position. If the motor is still on the boat, tilt it up to the maximum position as it makes replacing the gear box assembly a bit easier. Slide the assembly into the leg and keep checking all is going where it is supposed to be going.
Once the drive shaft is starting to engage the crank spline do not twist the gear box, instead rotate the propeller clockwise and anti-clock wise through about a 1/4 turn, as you continue to GENTLEY push the gear box, until it engages and slides home. Insert a bolt hand tight and relax, put the rest of the bolts in and tighten in sequence so as not to stress the casing and possibly fracture it, tighten to the required torque and your done.
IMPORTANT NOTE:- DO NOT USE THE BOLTS TO %26quot;PULL%26quot; THE GEAR BOX HOME. This may damage the spline if it not lined up correctly or strip the thread in the casing. Also if you have cleaned off all of the grease it would be wise to re-grease the spline with the recommended marine grease. I hope this is of some help.

I think I just need a general idea, it does not have to be that same year and HP.Changing the impeller on 1957 Sea King 25 HP?you need to take the lower unit off and the waterpump is on the top of the lower unit, unscrew the four nuts and carefully lift the housing up the shaft, being carefull not to damage the housing or the gasket. there is a shaft key that holds the impeller, take good care of getting the inner bowl housing up the shaft once you have the housing off take the old rubber impeller out and replace it with the new kit that you will get... after you replaced the impeller, put a little grease in on the rubber impellers and place the unit back on the shaft and with the shaft key in place. and replace the housing and becarefull tightening the nuts as you can crack the housing, only a 1/4 turn for tightening is sufficent. and you are ready to do the reverse process of mounting the lower unit back in place..Changing the impeller on 1957 Sea King 25 HP?Every engine I have heard of needs the lower unit removed.

If you succeed use lots of grease when reassembling and loosen the joint every couple of years to prevent reocurrence. cheers Pete.I have a 90 merc 45hp motor and lower unit seems to be frozen to power head.?Yes make sure you have all the bolts out. Should you get it apart, when reassembling it is important to grease the shaft splines but -VERY IMPORTANT- do not leave any grease on the top of the shaft. This grease will be trapped on top of the shaft and cause excessive load on the shaft resulting in major problems.I have a 90 merc 45hp motor and lower unit seems to be frozen to power head.?There is a bolt under the cavation plate,Then you must remove the shift lever.,(better not mess with it if you are not a outboard man

I have a Sears 7.5 hp outboard motor #217.58890, and I need to know how to change the impeller.?
This would be the 7.5 tecumseh or clinton??? (Ted Williams?)
That lower drops right off with it's 2 nuts removed. Now here is the tricky part. You might have a shifter, or at least a neutral.
They made several-- the worst was a clutch dog running on long splines on the top of the drive shaft. It clutched into an identical piece keyed to the crank shaft with a spring to help hold it in gear. SO-- if you drop that lower and hear a rain of parts coming down the exhaust, you will need to pull the power head to put it back together.
The next was a spring wound bendix. It should stay in place and cause you no problems. If any of it follows the drive shaft out the exhaust, then it's broken and you will need to pull the power head to replace it. If unavailable, you can have it welded together and it will be a %26quot;pull and go%26quot;.
Once on the bench, the water pump has 2 little bolts holding it down. The tall water pump has a roll pin holding the impeller, and the small flat pump is actually a mercury pump for their small motor. But that pump came in 2 shaft sizes.
Use lots of grease on the spline and slippery up the new pump.

How much would it cost to get my impeller changed?
I have a 1976 Mercury 1500 Outboard that needs a new impeller, I have a new impeller kit and everything. How much do you think a mechanic would charge to replace it and everything?How much would it cost to get my impeller changed?Most Marine dealerships post a %26quot;shop labor rate%26quot; That is what they charge per hour for the labor. This varies with region of the country and even from dealer to dealer. The Manufacturer has a %26quot;flat rate%26quot; time estimate. So many hours to do a job......Like 2 hours to inspect and change the impeller. Then there are additional times added in some cases for things like broken bolts or props that are corroded to the shaft. So. 2x$110/hr= $220......... The good news is that this is a job you can learn to do fairly easily.....Do it your self 2 X $0= ????. Good luck!How much would it cost to get my impeller changed?Get a service manual and do it for a fraction of the shop rate - as long as you are reasonably competent and have some good quality basic tools you will be fine.

How long would it take to change the impeller on 92 seadoo?
It shouldn't take more than about an hour...the trick is getting the housing off and making sure everything is well greased with white lithium grease before you re-assemble the housing.How long would it take to change the impeller on 92 seadoo?Hmm, someone giving you trouble with a labor fee?? LOL! I would say it should take about an hour. Take the steering cable off the pump nozzle, there will be four bolts holding the pump to the back of the boat, then you pull the cone off, stick it in a vice and using the spline tool you can remove the impeller. The wear ring may need to be changed, you have to cut it in 2 places and then sorta pry and punch it out being careful not to damage below the wear ring. Once it's out you can hammer a new one in and retighten the impeller in the vice. Should take an hour, maybe little over depending on condition of your boat, etc, etc... Hope it helps. Sea Doo SP???? X??How long would it take to change the impeller on 92 seadoo?less than 30 minutes.

How important is it to change outdrive fluid every year?
My boat is a couple of years old and I'm wondering how important changing the outdriver oil every year is. I've previously done it just because the manual says too but as a typical summer weekend boater I%26quot;m wondering how much abuse the gear lube actually takes. I have an Alpha drive and run High Performance Merc gear lube. I'm not due for an impeller change this year.How important is it to change outdrive fluid every year?I've been a marine Mechanic (Certified Mercruiser) since 1974 and but recently I've changed my position on this maintenance item. It's actually possible to check the oil for water, without draining and replacing. I've also pressure tested and vacuum tested lower units to check for seal leak. So, given the very limited amount of use, and the quality of the oil, I check but don't replace unless needed.
Edit. The above position was not taken lightly, but after years of experience and training........Changes in the lower unit oils, and an awareness of being more %26quot;Green%26quot; convinced me that %26quot;always%26quot; draining and replacing was not necessary in 2009.How important is it to change outdrive fluid every year?it's not so much the lube issue.. it's a water issue.
If water gets in and sits over winter... well you see where this is going...How important is it to change outdrive fluid every year?Servicing the lower end is the only time you will see if there is a seal leak developing or already happened. It is also a time to see if there is any excess metal fragments in the oil. Seals in particular give you no sign of failure externally until way too late - it is possible to unwrap the boat after winter and find the bottom end a seized, rusty mess requiring full rebuild or even total replacement. Not good.How important is it to change outdrive fluid every year?Let me make this very simple.
Lower unit/outdrive lube change $30 of lube and $1 to $2 for felt washers ($11 for the hand pump if you don't already have one) versus +$2,000 in replacement/repair costs.
I'll take the $30 a year over one outdrive replacement/repair anyday.
Not to mention you must check for seal leaks and the gear lube condition anyways annually.

The shiftrod has to be disconnected. Sorry not familiar with that particular model -- sometimes the disconnect is under the carb, sometimes there's an access panel on the exhaust housing just above the antiventilation plate.

Changing Impeller on a Mercury 4hp 4-Stroke...?
Due to the lack of the tell-tale 'squirt' of water from my outboard, I'm about to change the cooling water impeller on my 2006 4hp Mercury 4-Stroke Sailpower.
Where is it? It is the first time I've needed to change it - can anyone direct me to a diagram as to the position of the impeller or describe where/how to remove it?
Many thanksChanging Impeller on a Mercury 4hp 4-Stroke...?Hi Adam!
Before you do the surgery to replace the impeller, the check-hole of your motor may simply be plugged. I've had to use a toothpick to clear debris from our Honda15 many times. I change the impeller on our motor every three years and keep the old one as a spare. Unless you've run the motor without water... they're almost bulletproof.
It's not really rocket science to change one out. AFTER removing the prop...
1) Mark the position of the gearshift linkage with a Sharpie, then unattach it.
2) Remove the bolts attaching the lower leg to the main body and remove it.
3) Slide the impeller off the spline.
Clean old gasket off housing, use new gasket, reassemble in reverse order. Make SURE to attach and adjust gearshift linkage EXACTLY where you marked it!
Good Luck!Changing Impeller on a Mercury 4hp 4-Stroke...?The impellar is in the bottom gearcase. You really should buy a repair manual for this motor if you plan on working on it yourself. A repair manual costs about $25-$30 and will pay for itself many times over. You can buy one at a mercury dealer or www.selocmarine.com or several other places on the web.

How do you change an impeller in a Merc Cruiser 205 lower unit? Do you need to be a mechanic?
It's not that hard of a job, but if you've never done it before, it would pay to get a Service Manual and read the lower unit sections before you start. It would take ten pages for me to tell you all of the things to do, like put the drive in farward gear before you unbolt it. Down to %26quot;marking%26quot; the trim tab before removal so it can be re-installed in the correct angle, once done with the impeller job.

Remove these and lower unit should drop down you will then see the water Pump housing. Before removing clean shaft so you don't damage seal. I would also lube shaft. Remove bolts or nuts from housing and twist and lift. Watch for small key that fits in the flat slot on shaft. Pull housing and old impeller off and clean inside housing. Use a small amount of WD 40 to lube inside housing.
Replace impeller being sure to line up key on shaft. Now place housing back on and while turning shaft push housing over impeller. Doesn't matter which way you turn it as it will set itself right when you start motor. Install nuts or bolts and carefully re insert shaft into motor housing being careful to line up water tube, and shift linkage. Don't force anything,it should fit together without any binding. Replace all bolts and nuts then hook to water hose muff and start to make sure you have water coming from telltale hole.
Good luck.

Highly recommend you drain your gearcase %26amp; look for water. Suspect you might have a tiny bit of corrosion on the driveshaft that may have damaged the driveshaft seal.
If so, fix it now before it gets worse. When you get the driveshaft bearing carrier off, use fine emory cloth to polish the driveshaft, but only the least amount of polishing you can get away with.115 HP Johnson How to disconnect linkage for impeller change?Underneath the carburetor where it attaches to the block the controls linkage is attached to a rod with a pin through it.

then a nut and maybe a washer
the prop may be tapped off with a rubber hammer
if it is really rusty you may need a puller
good luckHow to change impeller on evenrud outboard motor?You have to remove the lower unit. The Impeller is located on the drive shaft and rotates clockwise. When you put on a new one as you push the case down over the impeller turn the drive shaft clockwise so it slide in easy. It good to use a little grease on the rubber ends to help it slide. Below is a link and it show all the parts. The case is the large black up left and has bolts holding in down. If, you going to do this, I would buy a kit with everything as some may be worn, including the plate under the impeller.
Now, to drop the lower unit, I not sure I can explain. I would remove the prop first, just so it out of the way. Shift to reverse and you may need to remove a retaining screw up in the engine that hold the shift rod. Remove the trim tab above the prop and look/mark how it positioned. remove the bolts holding the lower unit and it should be ready to drop. May need to tap on it with a rubber mallet, do not use a metal hammer, though it may work it can crack something. I put it in a vise with towels to pad and then do your thing. Good Luck.

Remove the lower unit, it is hidden in there and driven by the shaft that runs to the prop unit.
I strongly suggest you try and find a manual for it, I didnt and wish I had. It is not horribly difficult but some technical advice never hurts.
Good Luck.How to change impeller on evenrud outboard motor?Once you remove all the bolts you can find, try to pull the lower unit straight down. If it doesn't come down with little force you need to get some supervision. Forcing it %26amp; breaking anything will cost you more to repair than having a mechanic install the pump to start with.

good luckHow to change impeller on evenrud outboard motor?You have to remove the lower unit. The Impeller is located on the drive shaft and rotates clockwise. When you put on a new one as you push the case down over the impeller turn the drive shaft clockwise so it slide in easy. It good to use a little grease on the rubber ends to help it slide. Below is a link and it show all the parts. The case is the large black up left and has bolts holding in down. If, you going to do this, I would buy a kit with everything as some may be worn, including the plate under the impeller.
