The biggest problem with used marine engines is the fact that about 90% of them have had "raw" water pumped through them thier entire lives. The stuff is about a corrosive as anything you have ever seen. It seems like the worst ones are those run in "brackish" water...not all salt, for instance the Cheasapeake bay. Once that stuff is in an engine, it does not go away, it actually seems to corrode worse once it is drained out. I think the salts get into the metal. Soooo... unless you have proof that the engine was run with a closed cooling system with antifreeze...I would pass on them unless they are REAL cheap.
By the way, other than that, they are really no differnt than the GM crate engines. The cams give a pretty narrow power band, unually up around 5000 rpm.
Just my opinion,
