replacing rear floor in 67 cc mustang

We used to go to Pokagon State Park, Potowatomie Inn, I think it was called. Boy that is in the "way back" machine!

Glenn: I noticed you said "Lake James" eariler in your post. Would that be the one in Indiana? Used to go there as a kid. Nice place. There is another member here that is on that lake. Forgot his name. Has an older C/C. You could maybe hook up if I could remember his name....senior moment.

I ordered the Dr. Rot CPES product. The gentleman on the phone was very helpful to determine how much I should order.

I will screw the new floors to the stringers as per the factory design, and will use waterproof caulk or liquid nails between the floor and stringers and "freeboard". I want to be able to remove the floor (without cutting) if need be - in case maintenance of the exhaust hose is necessary.

smooth sailing...

HI Chris B -
THanks for your comments. It looks like the CPES is the way to go...it's relatively expensive so I don't want to buy any more than necessary.

I was actually talking about the two floor sections which are to either side of the engine box. But the same consideration for sealing will apply, obviously. The old floor is screwed to the stringers and wood floor supports - it comes up easily but requires removal of engine box as well as the side panels between the gunwale and the floor. The old floor boards are 3/8" thick- I think I found some plwood outside-board at Menards that should work.THe original floor has the old grey vinyl covering... i'll just put carpet over the new floor.

Unfortunately I let my other hobbies get in the way and did not work on it this winter. Now I have to hustle because we have the cottage rental on Lake James in July!!

Hello all,

Looks like there have not been any recent posts on the popular topic of floor replacement.. so I thought I'd start one!

I need to replace rear floor panels - the panels lie over the rubber exhaust hose under the floor which are attached to the output of the exhaust stacks. I don't want to glass these floors in, in case maintenance e.g. of the rubber hose is needed. I want to cut and treat the floors, seal them with h2o-proof caulk and hopefully no h2o will leak into the floatation foam!

I read about CPES for sealing plywood, but that stuff is pricey (about $50 for two-quarts I think, these floor pieces are going to be approx 2x6 feet, so total would be about 50 sq ft to seal top and bottom both sides).

Cannot come by any cheaper resin... Lowe's etc carry nothing like this. Anyone have any experience with any readily available "deck sealer" or other similar product? Polyurethane based products? What about the fiberglass "bondo' products readily available at auto parts stores (the reactant for these is I believe ... MEK? which as I understand, unlike epoxy products, the reactant of fiberglass resin can be be reduced to provide longer working time?).

Anyone ever use composite ("engineered plywood") products for floor, and where to get that stuff?

Thanks alot in advance to whoever answers!
