non-wood transom wood substitute

[fastglass]

If money is not a major concern, is there a substitute to replace marine plywood in the transom? A material that has equal strength and no chance of rotting, dry rotting, or getting water soaked ever?

Threre are several excellent choices that are becoming very common in boat building. Penske board and Coosa board are just two of the more common ones.

Penske board is now Airex PXc http://www.corematerials.3acomposite...ex-pxc-us.html

Yeah Change the transom !!
Shape can give strength !! By making a completely new transom using shape to make it strong !!
I did this a couple of years back , Have a older hull with a tired omc 75 on the back so changed the transom completely and stepped the motor back 500 mm ,went from 20" to 25" inch motor and from 75 hp to 115 hp has no water drains and works a treat . Have a small spalsh well and because of the extra motor height neve had any water in the boat ever . the smaller splashwell means more cockpit space to stand when fishing .
The transom is glass ,foam cored, and glass !!
No wood anywhere !!.
