Transom Height

[ScottM]

Regarding transom height and transom replacement, has anyone simply added a 5" section to the existing notch to raise the height without actually redoing the entire transom? Our 23' Sceptre originally had a 25" transom but the previous owner cut it down to fit a 20" engine. If we repower, we want to fix the height problem and, at a minimum, put it back to the original height. If, for example, the transom is not structurally compromised and does not require total replacement, can a 5" section be integrated into the existing transom and tied in to the plywood core and fiberglass successfully?
