Re: The subject is a 74 20 cc with some problems
Just redid my transom w/ plywood. It is the way to go. Strong, cheap and EZ. If you seal everything correctly - you will have no problems.
Then, if you want to - where you are going to bolt through or screw through the transom, - drill out these areas w/ an oversized hole saw ( from the inside not going thru the gelcoat skin ), and remove the 'round' pc of wood.
Fill this round, voided area w/ a mix of West System epoxy and cabosil, place duct tape or a thin, temporary pc of plywood 'patch' over it till it cures. Then, from the outside ( the gelcoat side ), drill your thru hull through this epoxy. Bed your thru hull, and you will have no problems w/ rot 'cause all thru holes will go thru epoxy not wood.
