I glassed the port transom cap piece back in. I used mat encapsulated 1/2 birch as a backer and was able to straighten out the cap by screwing the cap down onto the ply. The ply was previously glassed and screwed into the existing cap piece.

***Note: All screws were removed after curing and the holes were filled with carbosil thickened epoxy. Everything will faired out with epoxy and microballoons before painting.
