Ts6m vs Conbrio

Ohhh, ok. So I called around and found marine grade 3/4 in. plywood for $122 for a 4'x8' sheet. I really only planned on using the marine for reinforcing the transom to add support to the teak deck. The deck seems to strain the transom when you put weight on it.

Plan: Remove the existing foam for about 24 inches away from the transom,
clean everything profusely, fiberglass/epoxy the rear section and
transom, I'm planning on putting it on real thick, then cutting my
marine grade wood almost the same size as the transom and fiberglsng
it in, then rebolting my teak deck.

Good idea OR bad idea?

Great idea, You may want to get this thread over to the service and repair aisle so that the fiberglass pro's will be able to chime in...
You're headed in the right direction, I just haven't done any fiberglassing to my boat.....yet......
transom strengthing is a great idea, it'll also put a little more back there, Ácetone is a good surface prep before adding new fiberglass, I'd also rough up the old stuff first.....

MBowl DUDE that is freaking sweet you got a project boat for a great price. It sounds like you are mechanically competent so you should have a $10k wakeboat on your hands after the winter! The work you are doing to the floor will give her another 20 years of life easy. Some improvements over the current floor will last much much longer.

Great idea for supporting the swim platform.

Start a new thread in the service and repair forum. Take lots of pics and document your process to help others!

Oh I almost forgot, CONGRATULATIONS! :)

ts6m is a ski boat (period). Lowest wake on the market.

I've run mine for several years and could not imagine trying to wake board behind it. No room for bladders either.

Be careful on wood rot for this old of a Supra. Hvae it checked out carefully.
