See what your bilge can do. Next time you are in your boat take the hose of your galley through haul and open her up. See if your pump can keep up with flow and how it stands up over time. Did that today. Well, on my H36 the stock pump could not keep up....my second bilge pump kicked in and did well. I ran it for 15 minutes..I figure might as well find out now rather than in the high seas.My biggest suprise was how little it takes to sink your boat...really makes me a believer of adding a second if not a third pump.Do the above at your own risk...enjoy watching the water come in.abe
