I agree squeeg333.

I'm really starting to think an automatic bilge pump installed in this location is the answer. Remove enough foam core to the bottom of the boat, install a 4" PVC pipe with hole's on the bottom or some kind of stainless steel cylinder screen, bracket the pump to the pipe or screen or a sump box may also work.
A Tsunami Cartridge Bilge Pump 500 GPH would do the job.
Wire it back to the dash and plum the bilge out the side of the boat. Install a 4" screw - out deck plate in the locker to maintain the pump.
