Re: water pump/inpler evinrude 1994
I think it should be pretty straight forward. I have a '94 20 hp that I'm thinking is very similar...if not exact. The biggest problem I had was realizing how the plastic sleeve used to connect/tighten the shift linkage together. That sleeve must be removed to allow removal of the connecting nut to allow the lower unit to slide of the leg.
I fought that little part for a long time until I realized that it was split on one side from top to bottom. I just couldn't see it with my bad eyes! Just find the seam, get a small screwdriver in there, and pop it out. Do not loose it because the rebuild kit doesn't come with a replacement!
Also, do not put moly lube to the top of your drive shaft...it will be impossible to remove!
