Thanks for the info, I believe as well the problem was the screw holes.. I'm
going to look into doing something that means I don't need to replace the
wood as it actually gets pretty interesting in that area of the boat, most
of the wood has resin over it and molded very well.. its just the main part
of the floor. I believe its still quite solid.. not sure how to go about
changing the floor yet though as I have to still investigate.

thanks for the info..

some of the screws essentially came right out of the floor

I'm no expert on this stuff, but here's my two cents: The screws probably
wouldn't have pulled out easily unless the wood around them was rotten.
Marine plywood doesn't have any inherent rot resistance of its own; they
typically get that from coating it with a resin of some type. When you put
screw holes in a piece of coated wood, you provide a path through the
protective layer and water can wick in and set you up for rot. (Wood rot,
btw, is caused by wood-eating fungi thingies that are always present in
wood
and which tend to come to life when they get a drink of water. Pressure
treated wood works by infusing a poison into the wood that kills the
little
buggers off.) If you're lucky, the rot will be confined to a small area
around the screws and you'll be able to splice in some new wood or use
some
kind of filler designed for this purpose to repair it.
