Well took the boat out today and now I have water in the oil...again. This will be the third time for this motor. I am not sure if it is a blown head gasket or what. Hopefully not a cracked block. The motor was running like shit thats when I descided to check the dipstick sure enough water. Well if this motor is crap, I think I will cut my losses and maybe either switch to chevy big block or small block. I like the small block for a couple of reasons. One is for the fuel economy and another is because you can rev them higher. One drawback is torque. What kind of speeds could I expect to achieve wth a SBC coupled with a 12wj does anyone know. The Boat is relatively light, not sure on exact figures though and it is very low profile.
