Rule 800 G.P.H. Square Bilge Pump

The Rule 800 G.P.H. Square Bilge Pump is an essential piece of equipment for any vessel operator serious about water safety and vessel maintenance. Whether you're running a center console, cabin cruiser, or working boat, bilge water accumulation is an inevitable fact of marine life—from engine weeping and condensation to spray intrusion and rain. This pump removes water quickly and reliably, preventing the slow buildup that can compromise buoyancy, electrical systems, and structural integrity. For anglers and cruisers who spend extended time on the water, a dependable bilge pump isn't optional; it's foundational to safe, worry-free operation.

Rule's 800 GPH capacity delivers consistent, high-volume water displacement in a compact square housing that fits tight bilge compartments where round pumps won't. The pump operates on standard 12-volt DC electrical systems common to most recreational and working vessels, drawing modest amperage while maintaining steady flow even under modest head pressure. Its proven design prioritizes reliability over complexity—fewer moving parts mean fewer failure points when you're miles offshore or deep in a remote creek. The rugged construction handles typical bilge conditions, including debris-laden water, without premature wear or seizing.

Anglers, cruisers, and commercial operators benefit most from Rule's straightforward, modular design. Installation is direct: mount the compact 6 x 4 x 8 inch housing in your bilge, connect 12-volt power, and plumb the intake and discharge lines using standard marine hose. The pump pairs naturally with either manual backup or automatic float-switch operation—many experienced boaters run their primary pump on a switch with a manual Rule pump as redundancy in the cabin. This redundancy approach has saved countless vessels and crews when primary systems failed in heavy weather. Verify your hose size compatibility and bilge compartment dimensions before purchase; most applications use 1.5-inch or 2-inch discharge hose, and adequate water supply to the intake ensures peak performance.
