If you're looking for that fabled fountain of youth, give up-no magic water is going to make you any younger. But it's a different story for your bilge pump. Attwood, the makers of Sahara bilge pumps, have found a way to give these pumps longer life: Water circulates around the motor housing, absorbing heat to keep the motor cool. These 51¼2"-by-31¼4"-by-4" automatic bilge pumps, with flow capacities of 500, 750, or 1,100 gph, have a nonmercury, nontoxic float switch. The wires are tinned to resist corrosion and caulked to prevent wicking. The pumps work in salt water and fresh water. Price: $54 to $94. Contact Attwood at 616/897-9241, www.attwoodmarine.com__.
