500GPH Standard Bilge Pump - 12V

Customers talk about flow, they want the water out of the bilge, and
fast. Improved design and performance means that our next generation 500GPH pump will produce this flow at just 12V rather than 13.6V as previously required...more typical of on board voltage supply.

Our next generation of Rule pumps include check valves and to do this, we've created hidden air vent to prevent airlocking. Under each strainer tab there is a small hole that vents any air trapped in the pump housing preventing airlocks...and that's how we do it.

We have true electromagnetic suppression (EMC). We have a built-in thermal cell that protects the pump and the vessel when things get too hot.

We've re-engineered the inside and outside of our bilge pumps, starting with a blank slate. And we're just getting started

Great bang for your buck!
Swapped out my old impeller and this helped fix my overheating issue. Super high quality, fit like a glove. If you know what you’re doing it’ll take you an hour tops. Super solid for the price! Fit into my 1990 alpha one gen 1 outdrive on my 4.3 Mercruiser.
