Ryank-

I respectufully disagree with John B concerning the moisture meter. A fully stable & safe transom can show high moisture readings around places where water will eventually weep through such as thru-hull fittings, transducer mounts, etc. Bottom line is that most older boats made with wood transoms are probably going to show high moisture levels. Plus, anything source of water ( a puddle, high humidity, etc) near where you are measuring can throw off the reading. I would save your money and not spend it on a moisture meter.

The fact that your transom is flexing is the bigger issue in my opinion. Transoms should not move at all.

If I were you, I would take the boat to a qualified person that you can trust (do you know anyone in the restoration business?) who will give you an honest opinion about the amount of flex in your transom. Marine Surveyors are great for giving a broad overall view of a boats condition, but in my opinion the guy who will know the most about your transom is a person who fixes them on a regular basis. Obviously, the key is to find someone reputable who won't just say that it needs to be replaced just because they want your $$$$.

Where are you located? Perhaps I can help you find a good reputable shop.
