Re: [omc-boats] How to check stringers/foam?

I haven't tried this, but another thought that would be a lot less
destructive (if it works): Remove one of the bolts holding the seats down
and try sticking a pipe cleaner (the fuzzy wires used in arts & crafts) or
some other object that might show moisture into the foam. I'd recommend
trying one of the front bolts as both my rears were rusted in place and
ripped the lock nut out of the plywood when I repaired my seats 2 years ago
(both fronts came out easy). As I said, I haven't tried it yet, but its
quick and easy enough to be worth a try before cutting holes in your floor
(though that's probably the only way to be 100% sure....but then how many
holes do you cut and where?) Good luck!
