Well, I bought a C&C 37+ a few weeks ago and have been having nothing but trouble. It started with a fuel injector seal failure that allowed combustion gases to escape into the cabin. Below the injectors are pre-combustion chamber that where frozen in place requiring the cylinder head to be removed. While the head was out, I decided to do a valve job. And since the heat exchanger had to be removed, I decided to have it cleaned out at a radiator shop. There is an aluminum sleeve around the cooling tubes in the heat exchanger that had perforated. My understanding is that raw water circulates through the tubes and fresh water surrounds them. It seems there is fresh water on both the inside and outside of the aluminum tube, so I'm not sure if the perforations are a problem. The radiator shop guy wasn't sure either. It wouldn't matter, except the heat exchanger is no longer available from Yanmar and the cooling tube assembly is $1K, and can only be replace if (big if) I can get the frozen one out. What happens if I ignore the problem? The radiator guy pressure tested the assembly and it held pressure. Any ideas? I'm really desperate!
