I have a very old 12' aluminum jon boat with a 7.5 hp outboard (55 lbs.) <br /><br />Anyone know of any reason not to use a Trex Deck (the new decking material made out of resin/plastic/wood) 1 x 12 for the new transom? The old one was 3/4" plywood and is shot. I'll be using it in salt water. I'm sure Trex Deck material :confused: is not as strong as marine grade plywood, but for a light application like mine, am thinking it may be OK.<br /><br />Any input would be appreciated!<br /><br />Thanks,<br />Sterling

tashasdaddy,<br /><br />Thanks for the reply. It is about $5 / linear foot I found out. <br /><br />What kind of 2 x 10 did you use for yours, Trex, solid wood, plywood?<br /><br />Thanks.

I build transoms from 3/4" Okouma Marine ply, epoxy them togther to make a 1 1/2" thick piece that's far tougher than any solid piece of wood.<br /><br />After cutting to shape, stained and coated in epoxy it will not only last indefinitely, but look good as well.

Sunder,<br /><br />Based on the refernce of cost, me thinks Taddy used a 2 x 10 piece of lumber. Not Trex or Plywood but a 2 x 10. <br /><br />Remember one thing, nothing cheap is lasting. Do it right the first time and don't look back.

Trex is an interesting idea. You'll find that it flexes a bit and this might be worth considering before you use it.

Re: Jon boat transom

You guys are great--thanks for all the thoughts. <br /><br />Very old jon-boat, yes, but I found out some interesting history--seems like it may be somewhat of a gem. Called an "Aero-Line", it was made in the 50's/60's by a WWII aircraft float-plane designer using aircraft manufacturing techniques/materials/rivets. Definitely has that war-bird rivet look.<br /><br />Still in pretty good shape even after multiple add-ons, owners, and modifications.<br /><br />Thanks again.

I too would like to do something like this for my older 14 foot aluminum jon and could someone possibly post a picture of their work so i can see exactly how you attach this to the boat. thanks
