Saving the Transom Wood

I have an Aluminum fish and ski and I have a bad feeling the transom wood is rotten. I have already replaced all the wood flooring, all the foam in the bottom of the boat, all of the wood in the interior, all of the steel nuts and bolts, and resealed everything below the waterline with 5200. While trailering the boat I have noticed the motor (1989 Evinrude 120) bouncing on the bumps. After using the boat for two years I had to retighten the motor mount bolts and the bolts that tie the stringers to the transom. They were all loose. When they tightened up, they squeezed the transom in. I believe the cheap ply wood in the transom is rotten and when I tightened the bolts it crushed the wood. I can?t access the wood because it is incased in aluminum. My thought on how to save the already rotten wood was to drill holes from the top of the transom through the aluminum top sheet all the way through the wood and out the aluminum bottom sheet. I would drill a hole every half inch. I would put two large spot lights on the transom when I put the boat away for the winter. This would heat the wood up and over the winter dry it all out. In the spring I would tape the bottom holes then fill the whole transom with either Git-rot or a penetrating epoxy. That should stiffen up the transom with out having to cut the whole back of the boat off. Do you guys think this would work?

Re: Saving the Transom Wood

Your transom is definitely shot. Replacing the transom on an aluminum boat is generally not very difficult. After removing the motor and any fasteners that go through the transom, you should be able to pop out the rotted wood. It is swelled in there due to the rot so getting it to pop out will be the most difficult part. Are you sure you don't have any access to it from the inside? Here's mine http://i176.photobucket.com/albums/w200/ezmobee/New Boat/DSCF2505.jpg

Nope. I know of no way rotten wood can be made solid again, sorry man.

All that rotten wood needs to come out and replaced with marine grade or exterior grade plywood that is all sealed up with epoxy (or poly epoxy and fiberglass).

A few photos of what you are working on would be helpful.

Cheers!
