I have a boat I put a new engine in a couple years ago, the boat has a 280 volvo outdrive. I am close to buying a boat that has v-drives, but the engines need replaced, My question is, what would it take to convert the sterndrive engine to v-drive compatible? The old engines in the new boat are mercruiser 5.7 liters and my new engine is a gm vortec 5.7 liter. I know the exhaust manifolds are different, but I shouldn't have too much trouble modifying that, I am just wondering about the flywheel, coupling end of it. I am trying to get around getting 2 engines since I have 1 engine I think I could use already
