So I was approached by a coworker who is having some bad luck. They didn't get the boat winterized in a timely fashion last fall, and in Canada thats an issue, and now need some parts. I can see it needs manifolds and I will likely just have them buy a kit with risers and gaskets. It also blew out the frost plugs from the block, so what should I be looking for internally on this engine.

[FONT=verdana, geneva]For the people who may reply, its a 4.3 Mercruiser in an 18 foot Ba[/FONT]yliner runabout and thats basically all I know.

I have this posted on a boating forum as well. Some say just scrap the engine for a long block. I have also considered filling the cooling system full of acetone and seeing what happens.

I have no experience working on frozen engine blocks but I would think it would need a full strip down and inspection. Was it frozen all winter or did they thaw it and drain it after the initial freeze?

That's the 4.3 v6? If it is check Inter mountain specialties for parts. They deal with boat motors and stuff. If the manifolds are the same as a jet boat check out mean chicken jet boat forum there might be parts on there.

If it blew the frost plugs out, I would check for cracks on the block near and or between the plugs. Unfortunately u might not see them until the engine warms up a little

that exact thing happened to a friend of mine with the same engine. He thought block was ok after fixing the obvious then went for a spin to find the block had a hair line crack as well. I think it was a $10 grand bill for him if I recall.
