Thanks for the replys I'm glad It never started with don't bother or its a stupid idea!
K9 my p16 may possible have been done I could be wrong! Because behind the rear seat there is ply spliting that area into 3 sections right back to the transom
If that makes sense I havnt studied it to see if it looks modified.
It had old 75hp merc 4cyl on it most or all its life I gave the pervious owner a hand removing it and It sertainly wasn't lite! But unsure the weight differance
Red dragon was your transom strengthened for that lump?
Cheers pete
