One of our customers very kindly supplied us with these pictures of his transom, stringer and floor repair. The work was done at a professional level and his notes on the pictures describe the process.

Floor removed
Removing transom

1. Floor removed and fiberglass removed from inside of transom and side of stringers to access rotten wood.

2. Removing rotted transom with a gasket scraper.

Bad wood removed
Transom pieces ready for laminating
Transom pieces laminated

3. Bad wood removed. Existing wood to be treated with CPES*.

4. Transom pieces ready for laminating. Top pieces are 3/4″ plywood, bottom are 1/2″ plywood. Edges shiplapped.

5. Transom pieces laminated with L&L Resin* and treated with CPES*.

new pieces laminated to fiberglass
Cutting of the stringer

6. New transom and stringers laminated to existing fiberglass with mix of L&L Resin* and sawdust.

7. This stringer had to be cut up under the existing floor about as far as I could reach my sawzall and the new one fit in. Not a fun job, but easier than splitting the boat a and removing the entire floor.
