Hi all, so I’m new to the whole powerboat thing. Working my way through trying to make this (New to me) 70hp more bulletproof. This engine is converted to premix, with a new fuel pump, rebuilt carbs with new gaskets, needles, floats, etc. , but I’m still having trouble getting it to idle without the throttle cracked open. Tested the compression and came out with 75psi on all three cylinders (cold). Pulled the head off and think it might be a bad head gasket? Take a look at the photos, any input is greatly appreciated! Hoping she doesn’t need new pistons/rings....
