Johnson Pump 500 GPH Bilge Pump 3/4" Hose 12V Dura Ports

The Johnson Pump 500 GPH Bilge Pump with 3/4" Hose and 12V Dura Ports is an essential safety component for any serious boater or angler who spends extended hours on the water. Water intrusion is an inevitable reality in marine environments—whether from rough seas, rain, or normal condensation—and a reliable bilge pump is your boat's first line of defense against flooding and structural damage. This compact, proven workhorse has earned its reputation among professional and recreational boaters alike for consistent, dependable performance when it matters most.

Engineered with a 500-gallon-per-hour displacement rating, the Johnson Pump delivers sufficient flow capacity for mid-size to large recreational vessels, efficiently removing accumulated bilge water before it becomes a problem. The 12-volt electrical system integrates seamlessly with standard boat wiring and battery banks, while the durable 3/4-inch hose connection accommodates common marine plumbing standards. Dura Ports technology enhances reliability in saltwater environments, resisting corrosion and extending pump lifespan in harsh coastal conditions where standard materials fail prematurely. The compact 6 x 4 x 8-inch footprint allows flexible installation in tight engine compartments without compromising access or maintenance.

Freshwater anglers, saltwater fishermen, and cruising boaters benefit equally from this pump's reliability during extended offshore trips where continuous operation may be required. Installation is straightforward—mount in the lowest point of the bilge, connect the 3/4-inch discharge hose to through-hull fittings or overboard ports, and wire to your battery system with appropriate float switches or manual controls. The Johnson Pump 500 GPH (Model 32503) pairs effectively with automatic float-activated switches for hands-free operation, ensuring your boat stays dry even when you're focused on fishing, navigating, or enjoying time on the water.
