"I recently aquired a boat from a friend who was going to junk it. It is a 78 Baja with a 470 Mercruiser. I have read many of the posts in here about the 470 issues with cooling and electrical. I can deal with just about an mechanical issue that arises. (as long as I have a book) However mine question is more of a design question. The Doghouse was removed from this boat and is no longer around so I plan on fabricating one. So will I have issues using a marine plywood to fabricate this?

"Cool, I will keep that in mind, insulation is a good idea, I hadn't even thought of that. This boat isn't quite what I wanted, but you can't beat free. I was hoping it was going to be a deeper hull boat so I could take it out on bigger water and attempt to do some fishing from it. Oh well, maybe I'll just fix this up and sell/trade it for something more suited for fishing."

"Also, unless you want carb problems, leave lots of space for air to flow about the engine. If not, gas will perolate in the carb, making restarts a bear.

"There is a sound/vibration dampening 'paint' that takes up less space than conventional foam type insulation. It's called Silent Running 1000.
