"Converting automotive engines for marine use has never worked they are just to different."

What? You are kidding right? What do you think every marine V8 gasser boat engine is? Nothing but car engines with different cams, watercooled exhaust, etc. There are some specific changes to things like the freeze plugs to less corrosion-prone metals and thick layers of anticorrosion paint but they are the same blocks and internals. A Yanmar conversion makes sense but ain't cheap. The only light V8 diesel readily available is the GM. These guys http://www.peninsulardiesel.com/ do a marine version. What I am suggesting is find a GM diesel truck motor and buy the parts from them to convert it. Look under the marine kits link. Or just buy one from them. RT
