I'm having to pull my 1984 Bayliner Contessa Flybridge out of the water this week for dry rot repairs--which will be very expensive. The engine will have to be removed and the back transom will probably have to be replaced. A long time boat broker told me that Bayliner used regular plywood, versus marine plywood in this vintage boat. Can anyone verify if this is true, or elaborate on their findings through experience or having worked at the factory then--or perhaps owned a Bayliner dealership in that era? So far this is the biggest sin I've found in my Bayliner flybridge. Otherwise, it has been a complete jewel for our California Delta boaters' paradise!

Re: Dry Rot

Bayliners of this vintage are notorious for rot in the transom, stringers, and deck/sole. This is the case with many other makes that use the same construction.

Whether they used marine plywood or not doesn't matter: marine plywood is stronger and has water-resistant glue, but it still rots. The key is proper encasement of the wood in fiberglass, including sealing the wood edges where holes penetrate it.
