New guy, old boat, dead transom

Trust me on this one you don’t want 1 ½ inch of fiberglass transom on the back of your boat. To heavy all in the wrong place. I sure would not want to drill out holes in that much glass either for drains, live wells scuppers, trim tabs, motor, and God knows what else. More glass does not make it better it makes it worse. Go with marine plywood or the newer composite materials on the market today the have worked for 50 + years and more than ample to hold one or two motors on the back. If I was going to re do mine again I would go with the composite materials. As for Kevlar I owned a Hydrasport when them make them out of Kevlar really good material and very strong and light that part should work out fine for you. Good luck and enjoy you project remember to buy enough beer you will need it.
