two 2000 gph should be the minumum, bilge pumps are rated at 14 volts input, with no hose or head pressure. Corrigated bilge hose futher degrades the performace, by the time you add in the rise and run of the hose, you'll be luck if that 500 gph will pump 100, next time your at the ramp and have time, back your boat in without the plug and see if your bilge pump can keep up, you'll be suprised how porr they perform. I usually wire two pumps with separate harnesses, both hooked to auto and manual switches, use breakers rather than fuses, easier to reset rather than replace. mount one auto switch higher than the other and hook an alarm to it to let you know something is wrong.
