Johnson Pump 1600 GPH Bilge Pump 1-1/8" Hose 12V

The Johnson Pump 1600 GPH Bilge Pump with 1-1/8" hose and 12V power is the workhorse that keeps water out of your bilge before it becomes a problem. Whether you run a center console, cruiser, or fishing vessel, water intrusion happens—through stuffing boxes, deck seams, or unexpected rough conditions. This pump is engineered to handle moderate to heavy bilge water discharge, moving 1600 gallons per hour when activated, giving you reliable peace of mind during extended time on the water. Built by Johnson Pump, a trusted name in marine fluid systems, this unit has earned its reputation among commercial operators and serious recreational boaters alike.

The 1600 GPH capacity is achieved through a self-priming, centrifugal pump design that handles both fresh and saltwater applications without damage when properly maintained. The 12V DC power system integrates seamlessly with standard marine electrical systems and draws reasonable current, allowing it to run from standard dual-battery banks or through a dedicated bilge circuit breaker. The 1-1/8" hose port accepts universal marine hose, making installation straightforward—simply clamp fittings to your existing thru-hull or internal drain manifold. Compact dimensions (6 x 5 x 6 inches) and moderate weight of 3.4 lbs allow flexible mounting in tight engine compartments, under sole boards, or dedicated bilge boxes without consuming valuable cabin or equipment space.

Anglers and weekend cruisers benefit most from mid-range bilge capacity like this, especially on boats between 25 and 45 feet where manual hand pumps fall short and oversized 3000+ GPH commercial pumps waste electrical resources. The 1-1/8" hose diameter provides optimal flow without excessive intake turbulence, reducing cavitation and extending pump life during extended bilge operations. Installation requires basic marine wiring knowledge—12V positive and ground connections to a float switch or manual override—and a clean, protected bilge environment free of sediment and debris that could clog the intake. For vessels stored in high-moisture climates, boats subject to regular water spray, or any operation in rough conditions, the Johnson Pump 1600 GPH is a cost-effective, proven solution that belongs on your vessel's maintenance list.
