Rule Rule-Mate® 1100 Fully Automated Bilge Pump - 12V

The Rule Rule-Mate® 1100 Fully Automated Bilge Pump is the modern solution every serious boater needs to protect their vessel from unwanted water accumulation. Whether you're running a center console, cruiser, or fishing platform, this 12V pump eliminates the guesswork and manual intervention that traditional float-switch systems demand. After years on the water, I've learned that automated bilge protection is non-negotiable—it runs silently, reliably, and without fail, giving you peace of mind whether you're docked or miles offshore.

What sets the Rule-Mate® 1100 apart is its state-of-the-art water-sensing technology that eliminates the need for a traditional float switch entirely. The pump activates automatically the moment water level rises in the bilge and shuts off cleanly once water is removed, delivering 1100 GPH (4164 LPH) of displacement with zero maintenance headaches. This fully automated design means no mechanical switches to jam, no flotation mechanisms to fail, and no user intervention required—the pump responds to actual water presence with precision. The 12V configuration integrates seamlessly into standard marine electrical systems, and the compact 7 x 4 x 9-inch footprint fits neatly into most bilge compartments without sacrificing valuable storage or creating installation challenges.

This pump is ideal for anglers and cruisers who want dependable, hands-free bilge management during long days on the water, in rough conditions, or when the boat sits unattended at the dock. The high flow rate ensures rapid water removal even in situations where bilge water accumulates faster than expected—critical during heavy rain, rough seas, or after washdown. Installation is straightforward on any 12V marine system, making the Rule-Mate® 1100 an essential upgrade for fiberglass vessels, aluminum hulls, and center consoles alike. At just 1.3 lbs, it adds minimal weight while providing maximum reliability.
