Looking for the piece of flooring that the motor box attaches to. Piece is roughly 1 1/2” thick and 29” x 24” rough dimensions. Ours is spongy; our other alternative is to build a piece out of marine grade plywood (glue 2 3/4” thick pieces together).
Thanks, Steve |

Steve—I’m hoping those with guru-level experience can jump in if I’m off base here. Seems to me you’d want to avoid putting something that rots into an all Fiberglas boat. I’ve seen others use Starboard material for this. It’s strong and won’t rot. |

Its also not very strong when not well supported. I’d opt for ply instead for that panel over a 26” span. There are other composite options but they’re not cheap.

Yah—gonna need some reinforcement! Material Properties As noted before, StarBoard(R) is a homogenous sheet of polymer material. As such, it doesn’t rot, delaminate or swell when subjected to rain, spray or saltwater. The polymer is treated with stabilizers to protect it from UV damage and it will retain its color indefinitely. Cleaning is simple with a scrub brush or ScotchBrite pad and scouring powder. For tougher stains use bleach and water. StarBoard(R) is made from FDA and USDA approved materials. This means its fine for things like cutting boards, galley countertops or fish scaling tables. One characteristic to be aware of is that StarBoard(R) is not a structural material. That is, you will need to reinforce or support large flat areas of the material. You could use wood cleats underneath, but why introduce the thing you are trying to replace – the wood? When I need to reinforce a piece of StarBoard(R), I use a piece of extruded aluminum, angle or tubing, or a narrow piece of StarBoard(R) set on edge. |

Go with TRBenj. I know just enough to be dangerous here. Thankfully never had a problem with delamination on the SS!

Ply epoxied together and then CPES'd would be my choice. For added strength and water resistance, a layer of 6 oz. glass and epoxy on all sides would do it. Marine grade ply isn't really needed.

Thanks for all the replies! What is “CPES’d”- the fiberglass treatment you mentioned? I’m also inquiring through our local Correct Craft dealer- hoping that piece may still be available. Seems like a lot of the CC boats would have used that piece and maybe it’s a standard and still in use? Ours was always just not right (yeah I know we have put up with it for 20 years and over 800 hours...), and I suspect there was a manufacturing issue from the start. Our dealer “solved” the issue initially with a stack of washers screwed in under the floorboard.
Thanks, Steve |

Steve, Clear Penetrating Epoxy Sealer. It's a very low viscosity epoxy that soaks in deeply sealing the wood. It's also a fantastic primer for subsequent coats of epoxy. |
