The Transom
Where there are holes there is rot
This boat was originally equipped with dual 70HP outboards, then a single outboard, and then nothing but a lot of holes in the transom. Most if the unused holes were just filled with caulk; As a result lots of water got into the core. Moisture reading was over 80% or higher in areas around the openings. All of the bras drains could be rotated in place
