The melting ice, and other liquids, from the ice box in my 1984 H27 runs into the main bilge. In a 24 hr period, a good bit of water collects. The hunter bilge is shallow and rather flat, and if I'm sailing, the water runs into the storage compts under the salon bench seats. Ive tried several pumps, but they all turn on after too much water gets into the bilge and for my preference, shut off too early, leaving toom water in the bilge. Anyone delt successfully with this issue??
