Transom Repair 1984 Bomber Scout

[kyle23u]

New to posting.
So just got this boat(1984 Bomber Scout) this year and took it on Mississippi River and handled it surprisingly fine and found a leak by the time we got back and surprisingly didn't sink, the transom must've been really weak and rotted when I got it but the boat still looked great. The motor that came on it is 77' 75hp evinrude and that's over the data plate by 5hp I believe if the data plate wasn't scratched over to 70hp... online shows both 60hp and 70hp max for my boat depending on source. But now I'm wondering best way to fix this. I've got some experience with woodworking working in lumber yard and my brother has experience with fiberglass work on aircrafts but none of us are well experience on boats that much. I've watch many videos of people cutting from back and such. I haven't asked locally around really if anyone does transom or boat repair in my area, I live in missouri and not sure if I want to bother bc it would cost more than the boats worth most likely and i dont want to spend insane amount. Already got engine off and thinking about splitting the hull top to bottom between the seal if possible. Please let me know what would be my best options or advice!

If you love this boat enough to put a few (several?) thousand dollars and a few hundred hours into the repair of, pull the rub rail, pop the cap, take dimensions, demo, and rebuild. Otherwise, it may be a better option to spend your efforts and money on a boat in better shape.

You can rebuild that transom from the outside, without removing the cap.

You would cut the transom out, line the deck, sides and under the splashwell with 2x2 P/T lumber to screw the new transom to. Glass the 2x2s to the top sides and deck, and follow the deck 2x2 with SS screws

Now cut 2 pieces of 3/4 plywood to tightly fit the transom opening.

Staple some 1.5oz mat to the face of the first piece of plywood, saturate it and screw it to the 2x2s and clamp it to the splashwell. Use all Stainless steel screws.

Repeat with the second piece of plywood. Glass the new transom to the boat hull on the inside as best as you can. The cloth is more flexible than the mat.

Now grind the bottom of the hull, and the sides of the boat to allow you to wrap 4 layers of 10oz cloth. Cut the cloth to overlap the plywood 1/4" on the sides and bottom. The next piece of cloth should overlap 1/2 on sides ab bottom, and so on. Add a 5th layer if in doubt, as you want about 1/4" of glass over the wood.

Saturate and install the cloth. Fill the weave with resin, and finish with finishing gelcoat. Sand the crap out of it and fill any voids with poly putty. Paint for appearance.

Figure on 2 gallons of resin and a qt of putty and gelcoat.
