Fire Hazard 30 Catalina

[Ron T.]

I just purchased an 81 Catalina that requires a complete overhaul both inside and out. While I was painting out the engine compartment, I noticed that the top rear engine cover (the one under the counter) has a burn area in it the size of a softball. The burn area is located directly over the exhaust pipe where it turns downward into the wet exhaust. Although the exhaust pipe is wrapped in heat resistant material, I think the pipe is too close to the wood cover. I have since built a new wood cover and lined it with 1/8" lead sheating. Finding burnt wood anywhere on your boat is quite unnerving! Can anyone think of a reason why I should not lower this exhaust pipe an inch or so by shortening the hose into the wet exhaust, thus getting it away from the wood? Thanks for any help.

Something to think about

A couple of things come to mind.1. You can't be sure of the reason for the burn mark. It is possible that a former owner may have changed the exhaust pipe, but didn't insulate it at first. He later learned of the consequences and insulated it after the fact. If it doesn't get hot enough now with the insulation in place to burn wood, you shouldn't have a problem.2. Changing your exhaust pipe configuration requires careful consideration to avoid getting water in the engine and drowning the engine. Pay particular attention to that if you make a change. Good luck!!

Burn mark

We had a similar mark on our 30. But the pipe was old, and insulation bad. After replacing the pipe with stainless steel and new insulation, the cause was eliminatated. The old pipe was coming apart, but because of the wrapping, wasn't visible.
