How did the manifold crack? Did water get into the engine? Manifolds
(exhaust?) don't just crack without a reason. Are you planning to put
a new engine into the boat? Have you checked the oil to see what it
looks like? If it's brand new oil, I'd be very concerned that water
got into the engine and may cause huge problems.

A cracked manifold on an old Chevy 250 inline 6? How is that possible? Those
engines are rugged ol' beasts! I have one!

Let me know if I can help in anyway with the old 165hp inline 6.
