Check out the diesel engine classes for sailors at Mack Boring, several locations in the US.
The good news is that diesels don't have carbs or ignition systems. The bad news is that they have damn finicky high pressure fuel injection systems, which can be just as problematic if air gets into the lines or the fuel is contaminated, and fuel tanks will breed problems all by themselves.
You'll see plenty about that by using the search engine in this and other forums. Diesels are neither better nor worse, just different. Except, of course, to some of us they simply stink all the time. I've never met one that I couldn't smell, and I can't stand the smell of them.
