From Dave Howell, Nellie D. 37VT63
Just successfully tested a design for a Slurpee electronic bilge switch. It uses a GRI 2500 water sensor connected to a Beuler BU508TD 12 VDC automotive 4-Pin SPST time delay relay (with adjustable time delay). The GRI 2500 can sense water that's as little as 1/16" deep. As long as water is present the GRI 2500 triggers the Beuler relay. The relay turns on the Shurflo 3.6 GPM pump. The relay is set to continue running for one minute after the 2500 stops sensing water. During this extra minute, both the last 1/16" of bilge water and the Slurpee's tubing are drained. The two parts cost about $20/ea. I'm now looking for less expensive alternatives.
