Transom repair???

[SkunkBoat]

notice in the second picture how it is 2 pieces coming together on an angle. It does the same on the port side. So you see the transom is not one big flat piece of plywood.

I still can't tell from the pix if its shot. Mine was soft in the corners and I panicked but after tearing it apart I saw it was pretty solid down a few inches. Thats going to be your call.

If you go ahead, consider limiting your cuts to the motor well and not go into the hatch openings like I did. You might find you have enough room to remove much of the inside skin.
