Engine issues?

Hi all, we've got a deposit on a V-20 cuddy at an upstate marina. The hull is very clean, the previouls owner was as OCD as I am. The bad news is that when we went out for sea trials yesterday the engine kept stalling out.

The plugs were all oil fouled so the marina replaced those but that only seemed to make things worse. Then something in the starter circuit quit.

Net result is we haven't completed the delivery. The marina is asking that we "give them until Monday" to sort things out.

The engine is an '87 OMC 225hp V6 two stroke. I know nothing about these engines - I'm a rag boater who decided to go fishing. Help!

I'm told that it would take $10-12k to re-power the boat, which is way more than the marina says it is worth (although it's mint except for the engines - oh yeah, the 9.9hp kicker is kaput too)

The OMC outboard is mounted on a proprietary transom mount, so it's not a matter of dropping an new engine on the transom, I'd have to buy the mount too. Cha-ching! Not an easy DIY job either...

Am I walking into a mine field here? Anybody have any 411 on this OMC engine? I like the boat and I like what I'm reading here but I'm not up for replacing the engine.

Thoughts? Thanks!

Eric
