My 92 baja 240 middle floor board is rotted out. I just picked up the boat this past summer. Is this an indication the boat may have taken on some H2O ?? The old floor was coated with fiberglass, can I just replace with marine ply ?

Thanks

Put in new carpet and sell it...............

Probably just had a crappy or no cover on it for an extended period of time. Recoat it with resin if you want it to last.

I have had many boats over the years have rotten wood.... I use http://www.rotdoctor.com/ CPES will help out alot, along with thier resin
I use CPES on all wood, turns it into almost rock even if its rotten...
dont know whats in his mix but use a mask!

Been there went shaped out new piece of m/p I hit it with2layers of glass and add stringers to it real small 2x4 its sweet now been 4yrs mines a 88 doing new full height bulkheads this winter and back seat. art

Yep, happended to my 1991 boat as well a few years ago. Moisture just built up over time and use and the wood rotted. It was not marine plywood....... I cut it our and replaced it with marine plywood coated on both sides with glass and resin. Should be good for about 83 years or so! Solid as a rock.
