I bought a 17' smokercraft, and it has a few soft spots in the floor, rather than replace the bad sections, I'm replacing all of the floor with 3/4" marine grade plywood. I was wondering what any of you treated the wood with before laying the glue and wrapping the carpet?
Internet quotes are great, but most are untrue. "Thomas Jefferson"
I had a runabout that the floor started developing soft spots and I ripped up the old floor to see what condition the stringers were in. They seemed to be OK and wood encapsulated in fiberglass. Since all the structure seemed fine I pulled out the in floor fuel tank and added more flotation. Since the boat was open and stayed in the water for the summer I didn't want to put carpet in since the carpet on boats always seem to stay wet and will cause the floor to fail. I used 3/4 marine grade plywood to deck the floor and fiber glassed over top of that. After the fiberglass cured for a few days I picked up at the marina a floor paint that was rubber based and rough to prevent slipping. It painted on gray but was a black and white speckled when dried. I kept the boat for the kids for 5 years and the repair and paint held up the whole time.
If the stringers are soft you can repair the damage but JMO its not worth the time or risk.
