:cool:Hi I was wandering if anyone could tell me if a lower unit from a 1773 3 cylinder 65 hp mercury would fit a 1969 or 1970 4 cylinder 65 hp mercury with the same length shaft? Any help would be greatly appreciated.
Hy, I have a 1973 three cylinder 65 hp mercury. Compression is 115-120 psi in each cylinder. Its getting a lot of water in the top cylinder. Not checked the other cylinders but I think the are staying dry. Any help would be greatly appreciated.
