I had a guy in tiverton RI do the transom. He specializes in all types of fiberglass repairs including many types of transoms. The cut out for twin outboards on my boat i think was the prob. It is designed to have two motors on each side and not one in the middle, especially one that weighs 520lbs. This is why i think the hulls that came through with single outboards have a different cut out on the transom. This is just my theory i'm not sure.
