Floor in Jon boat

[GRANDPAOF7]

I am going to put a floor in a old Jon boat. Do I or should I seal the pressure treated plywood. Of course I am going to carpet it.

You shouldn't use pressure treated anything in an aluminum boat. It contains copper and it will react with the aluminum. Just use regular exterior plywood and seal it with spar urethane.

Check out tinboats.net's forums, its a site dedicated to modifying aluminum boats. You can learn more in 15 minutes on that site than you could searching for hours elsewhere.

Couldn't he just use regular ply? I would think by the time the wood rots the carpet would be crap anyway.

Unless he really beats the crap out of his boat, I doubt that. The carpet on my 95 Tracker is still like new, and I'm not even that anal about it.


Even if it didn't "rot", it still might warp or sag in some areas.

Buy 4x8 sheets of construction styrofoam, cut to fit interior of floor, it comes in 1/2" abd 3/4" and 1" thicknesses. To get your finished height, glue sheets together with aerosol contact cement, then glue a top piece of 1/8 underlayment plywood; it has a veneer grain/finish. Now you have a lightweight hard surfaced flat floor. If you want to hold it down, use some angle aluminum and self tapping screws screwed into the seat bulkheads. No need for carpet, just stain the underlayment, it's as water resistent as any plywood. The styrofoam is a sound deadener too.

I like that idea! Cheap and make sense.
