i have a 86 merc 350 it is somehow pumping raw water into the heat exchanger (log things?). last year i cleaned out the risers and replaced them with the wrong gaskets (had four holes to allow raw water in the lower manifold) did the exact samething overflowed the logs. is it possible my gaskets deteriated that fast allowing raw water in or is it something more expensive. just seems odd that i would have the same problem every year

Hello, are you getting water into the cylinders? Log things, do you mean the exhaust manifolds? Cool

I am looking at a Century Resorter That I am told has the same problem. I talked to the owner but he was more confused than I am. He said that he would get water up in the exhaust manifold after he would shut it off. I have a message to him asking for more details. He said it was just in the right bank and that it would do this after it had run.
Please tell me your thoughts.

This is typical of an exhaust manifold failure. We see this several times a week. Cool

Thanks for the reply.
I am correct in assuming in that case that I need to replace the manifold? On a scale of 1 to 10, how big a deal is this?

Hello, it's not a big job to change out the exhaust manifolds. Cool
