I am up to my shoulders in rebuilding the transom on my 65 Johnson tri-hull and have a major concern. it appears to have originally been only 1" thick plywood but it did have a 2x6 beam laid on edge in front of it.
is 1" thick enough if I replace the beam with a 1 1/2 x 9 1/2" LVL and tie it to both the stringers and the sides? I was thinking it may be since it is right under the splash well and located smack dab in the middle of the transom. I also wonder what would be the best way to tie the beam to the stringers. it is about 6 or 7" off the floor. should I use steel or some form of wood covered in fiberglass. BTW, I am upgrading the transom by covering the inside with glass, it was wide open which I feel may have contributed to it's failure.
also I should mention the engine; 1966 Johnson 100 HP v4 which according to the owners manual weighs 272 lbs.
