I've written on this subject many times and wish I had it saved to repost.
My 69 Rogue was mildly waterlogged. The wooden components in the floor had
rotted from years of standing water. There is a drain running down the
center of the hull on the Rogues - it connects the front bilge to the rear
bilge. I would drill a small hole somewhere in the floor above the most
dependant part on the hull - maybe toward the rear in front of the engine
compartment. I would use a forstner bit that you can get at Lowes - maybe a
half inch or one inch diameter on an extension. Drill lightly till you hit
bottom and the bit should chatter rather than dig into the fiberglass on the
bottom which is pretty thick and tough. This will act as a well and any
significant loose water should rise in this well over say 24 hours. One
reader mentioned smell and he is right - I found a fishey smell when I did
mine. I ripped up all the floor and replaced it all back to original
specs.all myself. It is solid and as good as the original I feel. There is
a pair of stringers running the length of the floor and they align with the
engine mounting pads in the rear. If the boat runs fine and pulls skiers OK
then I would leave well enough alone. It does no good to find water if you
are not going to rip it all up and fix it. One thought about the seats and
their mounting bolts. They screw into 't' nuts on the underside of
reinforced plywood. Mine were mostly corroded and if you can get yours out
without a lot of rust or corrosion on them then that is a good sign. Also
there are long bolts in the engine compartment that mount the engine pads to
the floor. Pull several of them out and look for water there. Mine were
rusted but came out fine. Be careful, if they are frozen, then go to one
that comes out. You do not want to bust off one of those babies. I replaced
all mine with stainless steel. It doesn't hurt to use a little liquid wrench
or other bolt loosener. Be patient and let it soak overnight. Hammer on it a
little and go slow. You should really be out on the water with the boat now
anyway. Save all this stuff for winter! I'm hoping to put the Rogue in the
river tomorrow. Time to ski. TK
