The Famous Potter Built Rotten Transom

I'm knee deep in a a refit of my 1974 20cc. My transom was soft, and I decided to convert the 20" cut-out to a full transom with a bracket. I did an exterior job, since the skin was cracked at the corners of the cut-out.

To answer your question, I used a carbon/composite material called "Penske Board" as the core. It's dark grey in color, easy to cut (wear a mask!), and I used single piece 1 1/2 thick, (along with fiberglass cloth inside and out, and a prefabed 1/4" sheet for the outside skin). This stiff is strong! and much lighter than plywood. And with all the glass I have on top of it, I feel confident shooting a screw into it (I'll keep you posted, since I haven't mounted any hardware yet, worst case I'll thru-bolt).

There are some pics floating around this site of my boat, and I'll be sending more since I have my B-Bracket bolted on, and this week I should install the new fuel tank.

Good luck!
