    If you're referring to replacing the transom core then this is one way to do it and usually easier then removing the inside.

    pistnbroke I try

    No problem as par says this is one way to do it I have the 16 ft version of this boat in Noosa ..but in the end there will be some crawling under the engine splash well. Cut two peices of 22mm ply to the right size and push one into the hole about 30mm to the outer face from the original transome outer face ..get it all square and fibre glass around on the inside ( crawl) not sure how you are going with the floor you may need to take about 300 mm of that up....then with the next ply sheet about 6mm smaller put oversize sheeet of 500g fibre glass over the second sheet with overhang of fibre glass and push it into the hole with the glass wet . Screw around the edges and centre to pull the two together (most important ).. then glass the egdes of the overlap glass into place. Now glass over the outside of new transom with two layers of 500g ..sand and fill and spray ....then sort out inside glassing over the inside of the transom . then sort the floor out giving support to the transom.....easy .forgot to say ..clean up the area where the new glass and old meet with an angle grinder and wipe with acetone to soften before you glass it in ....you may loose a few mm in length doing it this way.
