  • Works perfectly.
Style: 1100 GPH
Easy install. Works great.

  • Great pump in a small package
Style: 1100 GPH
This bilge pump is over a third smaller than the one it replaces. The old one just died. This one functions well and the extra space around it makes cleaning the bilge and the intake strainer far easier.

  • No float switch bilge pump
Style: 800 GPH
I love this bilge pump. My boat stays in a slip and has several leaks I have not been able to pinpoint. Every 45 minutes this bilge pump comes on and runs for about 50 seconds. This pump has been dependably doing this for right at two years 😎 ! ! !

  • Bilge Pump Replacement
Style: 500 GPH
Had to splice the new pump into the existing wiring, but other than that, what a great upgrade to an automatic bilge pump. That's one less thing to think about while on the water!!

  • Better then expected
Style: 1100 GPH
Bought this hesitantly thinking it would be to small for my boat, but it works great pumps out faster then the original pump from factory. Due to the design on my boat my bilge takes on water when the kids climb in and out of the boat soaked in water and this pump keeps it nice and dry

  • Works fine but won't last.
Style: 1100 GPH
Most automatic Rule pumps seem to last about 1 year for me. If you want a pump that lasts longer you'll need a separate float and pump.

  • Nice little unit, minimal battery drain, easy install
Style: 500 GPH
Very nice little unit. Installed in 13’ skiff; keeps her dry with minimal battery load. Recommend.
