Rule Rule-Mate Automatic Submersible Bilge Pump, 12V - Available in 500 to 2000 GPH

The Rule Rule-Mate series delivers fully automatic bilge pumping without the hassle of a separate float switch. Each pump in this line uses built-in Auto Sense Intelligence that monitors water level electronically, switching the pump on when water rises and off once the bilge is dry, while a backup timed cycle keeps working even if the sensor gets fouled. Rule-Mate pumps run on standard 12-volt DC marine electrical systems and are built for continuous submersible duty in bilges, live wells, and other wet compartments aboard boats of all sizes.

All models share the same reliable, self-contained design: a compact plastic housing, threaded discharge fitting for standard bilge hose, built-in thermal cut-off protection against overheating, and a low-profile footprint that fits tight bilge spaces. What changes across the line is pumping capacity, sized to match boat length, bilge volume, and the amount of water you need to move per minute.

Sizes & Options

Choose your Rule-Mate pump based on the flow rate your bilge needs. As a general guide, smaller boats and secondary bilge compartments are well served by the 500-800 GPH models, mid-size boats and primary bilge duty typically call for 1100 GPH, and larger boats, deep bilges, or high water-intrusion risk situations benefit from the 1500-2000 GPH models. Match capacity to your bilge volume and typical intake rate, and when in doubt, size up rather than down.
