Product Overview

RULE INDUSTRIES 240 GPH Self-Priming Dry Bilge Pump with On/Off Switch

The number one question from Boaters at Boat Shows is "How do I get the last bit of water out of my bilge?" Rule now provides the answer. 

A Dry Bilge is a clean, odorless bilge. Rule now offers the best, most effective method of removing almost all of the water in your bilge, leaving 1/8” or less, keeping your bilge fresh, clean, and dry. The 4 GPM pump drains the bilge almost dry.

The filter-free design is self-priming to 9.5' (3 m). It is able to run dry without damaging the pump. The backflow protection reduces water coming back into the bilge. The connections are 3/4" (19 mm) hose barbs for the pickup and discharge hoses.

Rotating pump head and ports allow for custom configuration. Compact and simple design. A 90° thru-hull fitting and a Dry Bilge on/off panel switch is included in the box. Hose and clamps needed to complete the installation not included.

  • Filterless design; able to evacuate bilge water and odor
  • Self primes to 9.5' (3m) lift
