Re: Good deal? Need advice.
An inboard diesel replacement means a fast $15,000 and a lot of effort on top of that. Unless you really feel up to a DIY on that, or get lucky and it "just" needs a new head. Either way, if you can get a boat with a working engine for just a few grand more...that's a no-brainer, the engine will prove to be convenient. And add resale value when and if you eventually move off the boat and sell it.
The epoxy and paint routine also means that PO was a cheat, and the guy he sold it to wasn't so sharp on maintenance issues, so you've got two more reasons to question everything on the boat.
Unless you really want a project...walk.
