mn, Couple tips from a shade tree mechanic. 1 drain the grease from the lower unit. 2 lay the motor down on it’s back and take the cover off the front of the lower unit. The cover has the vent plug in it for the lower unit. Under that cover you will find the shift pawls and some springs and pins. TAKE some Pictures! If you don’t do this the pins and other stuff falls out on the floor and you will have a bitch of a time figuring out how to get them back in correctly! (Don’t ask me how I know this.) 3 Pull the power head. Some guys say ya don’t need to do that but you will need all the help you can get, pulling the PH will help. 4 Next put the motor back in your stand UPSIDE down. Tighten the transom clamps good. It will help you when you are working inside the exhaust housing. The impeller is high in the gear case, you will need some fancy tools to get a spanner nut and the impeller cup out. Be patient, it can be done.
