Aluminum transom has had heat distortion

Make a new plywood insert.----Make this piece curved.----Test fit with screws in existing holes.----Might look nice.

What do you mean "the whole piece"?

I meant taking the whole rear panel out, to avoid having a seam that could open up from being torqued around by the motor.

Thank you all for your input. To tell you the truth, my dad is in hospice and this boat project sort of serves as moments of relief as I am able to work on her.

Sorry to hear about your dad. I understand getting burnt out on the project.

It looks like the planned cut will be along the bottom edge of the transom. I think this will make a bad stress point because all of the leverage is going to be right on the seam. Maybe cut a piece of aluminum to fit the whole transom area on the inside, cutting around the braces, and then do the sheet on the outside to replace what you cut out. Talk to your cousin about that, and what he thinks will be a good structure.

Why is the coosa only half the height of the whole transom area?

Hey Mike, Thanks for the sentiment, and for the advice. I agree, it might become a stress point. I’ll have to think about it.

The Coosa being only partial height, I can’t remember exactly why I did that. The original wood transom sat above the knees and was only about 8” deep, maybe I just though I’d replicate it and dip it in the center.

I do understand the concept of taking on a project with an anticipated happy outcome with a view to lifting ones spirits...been there (still there). Sorry to hear about your Dad .
The boat ....after getting the heart involved ( I dont really know how to say what I mean ) I think I would get me a sheet of quality ½" marine plywood and a box of stainless nuts , bolts and washers and sandwich as much of the transom as I could both inside and out. Couple of tubes of sealant and Bobs yer Auntie

Thank you MC Tool. Appreciate the regards for my dad. Yes, I think it'll still be a happy outcome. Part of the distraction is learning, shopping amazon and other sites, watching Sampson Boat Co. build Tally Ho. All good stuff.

I would back cut and weld.

shouldn't be a problem either......check the transom for movement when you goose the engine, like you are trying to get on plane fast.
