Tsunami transom replacement

Ditto what will said. You can make a 4"-5" half moon cut out and still be able to put in your drain however the out drive may get in the way.... not sure how much room you have. If you don't have enough room for that then simply put a big limber hole in the center keel near the transom and place your drain plug off center a bit. I think the keel should tie into the transom. On the core, I've always made up the entire core first by laminating the 2 pieces of 3/4" ply with 1708 between the two. then glassed the core to the transom. Keep the pice coming Capt mac.

It will be easier to do and get a good bond with the 2 sheet's of plywood laying flat.

If your putting a transom cap on the boat and I assume you are. It will be much easier if the transom core is cut down at the top, below the outside skin the thickness of the top cap core with the proper camber cut in it.
The creates a shelf for the core to sit on and have a even bend to it. It also helps so that the cap matchs the washboards.
