anyone, I have an unrelated MB question

[Sooty Taillight]

I'm posting this question here because I think there are quite a few good mechanic that can answer a question, here it go's.....

Recently, I was hired to install a rebuilt marine engine into a boat.

The old engine had thrown a rod. It was a late 80's GM 350 CI gas engine. We ordered a long block replacement that was a rebuiid. I transferred all parts including water jackets, intake manifold, carb, fuel pump transmission, etc.

The owner ran the new engine not realizing that oil was leaking out from around the oil filter. It all emptied into the bilge all while he was operating the engine and running it at about half speed, about 2000 rpm. All of a sudden the engine stopped and now it is seized. If I click the starter off and on real quick, I can see the flywheel turn but only a little.

I would like to think that I need only remove the crank shaft, pull the pistons, send the crank out to be turned, buy 2nd oversize main, rod, bearings, I'm not shure about wrist pins, and reinstall.

I base this on hope that damage is localized only to the bearings.

Can anyone with knowledge about this type senario give me advise?
