The boat is a 1991 Chaparral 1800SL It's been sitting for years. I'm pretty sure the engine is going to be junk(it sounded like a diesel when I heard it run, tons of knocking) but I'd like to know what it is so I can research either parts or swappable replacement engines. I don't see any model designators on the engine but I might be missing them.
Any help Identifying would be greatly appreciated. Let me know if there's any better info I should be providing.
