Anyone know how to tell if there is mare than a little water under the cabin floor of an '05 353?

I bought a 353 that had been out in the weather all winter and the cabin floor was soaked this Spring. The bench seat cushions obviously do not come out and I'm not sure how else to check. I know how the drain system works back through the boat between the stringers but what about on both sides of the stringers. Could water still be trapped in there?

Any help would be appreciated.

The bench seats do come out feel around between the bottom and the back toward the ends of the seats there are phillips screws.There are also some under the front of the bottom.

As for the water all Formulas seem to get some A lot of guys have resealed there windshield and that has helped.I think it also has to do with the fact they are built very tight so it could be condensation.Take the seats out dry what you can and leave some moisture bags hanging in the cabin.

Pull the carpet back in front of the step if in the cabin looking into the cockpit, i bet you will find an unsealed hole there that waier comes in the cabin from the cockpit area.....

On the 353, lift open the step. You will see a hose from the head drain, and a fitting facing the stern of the boat. That fitting is a drain from the bildge, if the passage is open from the bildge, and the drain plugs are in, it could have back drained to under the step and into the cabin.

Theory? I don't know, just a guess!
