Under the cavitation plate there will be 2 bolts on side and sometimes one in front and possibly one under trim tab if you have one or in area above prop.

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.
