Equipment Notebook by David Ayers Photos by author. Bilge Pump Notes Y was the day I decided that one bilge pump was not enough for me. When evaluating your needs, remember that manufacturers rate their pump’s capacities under laboratory conditions. Fittings, elevation, voltage, hose types, hose bends and long hose runs can reduce the flow by 50% or more! Don’t forget to check the operation of automatic and manual switches regularly. (1) A mounting base has been epoxied in where a bilge pump or mounting plate can be secured with screws. (2) For this install, a mounting plate (high density polyethylene) will hold two pumps and two switches. (3) Position mounting plate and check for fit before attaching hose/wiring. Wire as per instructions. (4) Use smooth bore hose, if possible. Corrugated hose alone can reduce flow rate by as much as 30%. (5) Keep hose “bends” to a minimum. Use stainless steel clamps to secure hoses. Check for cracks regularly. (6) Ensure your bilge pump switches are fused properly, clearly marked, and easily accessible at the helm. ears ago during a summer squall, I received an alarming call from the marina, “Come check on your boat!” When I arrived, two boats were submerged and others were in big trouble. Waves broke over the transoms of many boats including my nineteen- foot Grady. My bilge-pump was running, and the self- bailing cockpit tried to keep up, but a clogged scupper or bilge-pump failure would have sunk me… literally. That OCTOBER • NOVEMBER • DECEMBER 2 0 1 7 29
