I get two qtrs.. or so in the bilge and if I don't pull the drain plug on the ramp, it will run forward before I raise the trailer up. I always store the boat with bow high and that stopped my water problem.

Mine was the hatch, pretty sure its fixed.

I agree I always do that and when back at the shed I never have water. But then I never have bilge water anyway unless it rains or lots of swimming.
