Crack in Manifold

[ThomasHill]

Finally had a day off without rain so tore into the boat I just got. The prior owner said it wasn't winterized and I found a core plug in the bilge. I removed the exhaust/intake manifold to replace them and get a closer look at the block. No evidence of a crack in the block. Just the 2 core plugs needing replaced. However, on the underside of the manifold in the center port I have a crackrunning all the way to the body of the manifold. Is this a candidate for JB Weld or should I look for a new manifold? The engine Model is a MCM120 and the serial is 4647625.

Hi Jack,


You need to replace the manifold.
