I replaced mine. It's a lot of work. Given the age there is a good chance
you've got some rot in the plywood in the floor and possibly the transom. A
lot of people would just live with it until it becomes big problem. Once
you dig in you usually find out you need to replace the floor, maybe the
transom, maybe some stringers. I ended up replacing the outboard stringers
and renforcing the inboard ones after saturating them with epoxy. My
transom was ok. If you do start it, use epoxy not polyester resin. Visit
US Composites for some good prices on epoxy.

Good day,

In regards to my project boat (75 sunray 15'5) I'm wondering what others
think about wooden floors, and when to change them. From what I
understand
the floors of all these boats are built with marine plywood thus they can
take a beating being wet. Now that I've covered the boat I'm letting it
dry
up good, and will be ripping the carpet in a little bit. The reason I'm
curious about the floor is that when I pulled out the back seats, some of
the screws essentially came right out of the floor as I suppose enough
water
was around them. Going forward I either dry up all the wood, clean, and
paint it then re-carpet, or I look at changing the wood floor (which I do
not prefer to do). I can stand on the floor with my my weight (over
200lbs) and as expected the floor may give a bit in places where there is
no
extra support underneath but plywood typically has some flex right. In
any
case there's no gaping holes or worn out areas in it, just some screw
holes
that appear to be a little weaker around them.

Any ideas?

I have thought about taking out the carpet, waterproofing the existing
floor
after a thorough cleaning and maybe even leaving the carpet off (as it
always soaks up water rather than letting the water go away.

Water probably wicked into the wood through the screw holes.

Marine ply is built with waterproof glue and there are not supposed to voids in
the wood, so there's a chance the rot didn't spread far beyond the screw holes.

Even so, that won't matter much. Odds are you currently have screws just
exactly where the screws need to be in order to secure the floor to the
framing. If those points are compromised, it wouldn't matter much whether the
remainder of the floor is good or not. You could fart around sistering the
framing, etc, but that would be way too much work to go through just to try and
save a 20 some year old piece of plywood. Start over. :-)
