Transom repair

[ScottM]

bobhoff,
First off, welcome to CSC. Regardless of what type of boat you may have, you'll find some excellent advice here, especially transom repair/replacement.

The most obvious sign is excessive transom flex. Stand on the trim plate of your motor and jump up and down. Another sign is moisture in the core, which is picked up by both a moisture meter and by tapping on the fiberglass with a plastic or rubber hammer. With the hammer, you will hear a hollow sound due to delamination. Yet another sign is dirty water weeping out of motor mounting holes and other thruhulls in the transom. The best way to detect moisture is by driling a couple core samples.
