Best Method to fix a cracked Transom

[pisces3d]

I bought the boat, the marina owner removed the engine as part of the deal so that it could be safely towed from mississippi to new orleans. It is going to need more than the pourable stuff bc of the cracks near the engine mounts. I'm thinking about cutting off the outer skin, repairing the inner skin, then either fixing the outer sking and pouring it, or replacing the wood then the outer skin. I couldn't pass it up for 1200.00, even the Ocean Pro 200 is prob worth at least that. Thanks.
