howlnmad ,thanks n the compliments, I am trying with alot of help from the forum here. The transom at that point was my beginning point before I found all the rest of the flooring and stringer problems.This was before I tabbed it. I tabbed it with 2 layers of 1708 and a layer or 2 of chopped strand , can't think of the number. I did strip it all the way t the hull. I found out what was suppose to be my thickness which I believe was 1 1/2, not exactly sure ( a while since i did it ). if so i used 3 1/2 pieces of pressure treated plywood. each piece i fiber glassed,sanded and fiber glassed again, and screwed them together in areas that would not interfere with mounting parts later .then i either attached it with 5200 by 3M or fiber glassed it. then i tabbed it to boat.and i used 5200 around some of the outer spots where there may have some water at times. i hope this helps. any ?'s, i will see if i can help
