Posted - 07/30/2019 : 14:16:56 I purchased anew motor and bracket. I will remove my old bracket and replace with a higher rating for the new motor(Tohatsu 9.9-25 inch shaft). I was going to mount a 1/2 inch piece of starboard on the interior and between the new bracket and the transom. Any thoughts on this idea? Any experience with Starboard?

FWIW, I used 3/4” for added stiffness and it moved my 9.9 Yamaha 4-stroke a little further away from the transom and rub rail. Power head just clears when tilted.

Posted - 07/31/2019 : 06:37:22 I did that for my 110 lb. high-thrust Honda with Starboard, cutting it with a curve that followed the edge of the transom so the board extended a few inches below the bracket. The forces on the hull are at the bottom of the mounting plates on the outside of the transom, and the top on the inside where the liner isn't as strong as the hull. The 25" shaft increases the leverage from the thrust. I think a smaller backing board is a good idea for the upper bolts inside, and I don't think is as necessary for the lower ones. I rounded the corners and edges on the inside backer to minimize point-pressure against the slightly concave surface. I used a plastic-compatible sealant near the edges and around the bolt holes on the outside board. (It might even reduce vibration noise on the hull.)
Somewhere I was led to believe Starboard is formulated to resist UV damage or discoloration, where a kitchen cutting board might not be--especially a white one.
