Re: Buying a boat with a non running diesel
What Alex said. Five grand, easy. Ten possible. 12-15 also possible. I'm told that everything costs more in Hawaii, and finding a competent honest diesel shop anywhere seems to be a real good trick.
Diesels are somewhat less complicated than gasoline engines, but instead of an ignition system you have a high pressure fuel injection system and the FI pump can be damned expensive. Like a grand. the rest of the engine, bearings, shaft, valves, block, manifolds...all very similar. If you're planning to DIY it certainly can be done, but you'll be sending out the injectors and pump for overhaul, those aren't DIY. With the typical raw-water cooled engine, there's a problem that the cooling passages may have rotted out the block, in which case you can't salvage it, you need to replace it.
Which comes back to the prices Alex said. If someone hasn't maintained a diesel, they've used up a very expensive engine. If it has been maintained, 5-10,000 hours is typical and then it can be overhauled for that many more again. "If".
