This is around a 1995 - and what I see is just a dribble of water coming out from the check port. And, the manual diagram shows a hose coming down from the engine - I dont have any hose. I also see a pretty good spray of water coming out of a spot on the drive shaft thats above the anticavitation plate and just below that next metal ridge above the plate - that should not have water coming out right???? The motor just ran for about a half hour ok. Although I will also mention at higher rpm's the engine is revving up and down alot - any idea whats causing that?
