I'm in need some advice. I have a 21'Slickraft "1973" with Mercruser package "888"<br />302 Ford. Engine sucked-in salt water and I bought boat from a friend in this condition. The outdrive seems fine although shaft is allowing oil into gimble area, freind said it worked well. The 302 is no longer available, I don't want rebuilt, I would like to buy new engine,manifolds, risers ect...and freshwater cool kit for headache free ride. Everyone says go to a 350 chev. Please help with your Ideas. Thanks
