How do you fix a rotted transom?

Repairing A Rotted Transom One method is to use a product like Git-Rot from BoatLIFE.

You can inject Git-Rot directly into the wood for more thorough penetration.

How thick should a transom be?

Outboard transoms are pretty much standardized at 1.5″. Most use two layers of 3/4″ ply, but a stronger method is three layers of 1/2″. Transoms are typically reinforced with knees, usually a couple at the rail and two or three on the bilge stringers, to transmit torsion loads to the bottom.
