WOW !
This is turning out as good as a "What wood ?" or "Which resin ?" thread !
Guess I thought that the location of support (with transom saver) on the LU, wasn't the right place for support, that it should be up on the transom / motor swivel ...
My old transom from G/C was two half inch sheets screwed together with four screws, tabbed and glassed over, where stringer attached to transom the drainage holes were over an inch above floor (lowest spot) and holes were not sealed.
The wood was rotted, with just fiberglass for support, the transom was still solid (passed the hang all your weight on it and try to make it flex / move test).
My new transom is two 3/4 inch interior ply sheets with biaxial between them, which I would guess is twice as strong as original design ...
Plus I only live 3 miles from Miss. river and less then 10 miles from St. Croix river, with one trip to Red Wing (under 40 miles) once a year.
Funny about Ranger wanting transom savers ... My Brother had a Ranger, he installed a radio in dash and kept the piece he cut out ... It was over a half inch thick ! That boat was built like a TANK !
I like this idea / design ...
