Johnson Pump 750GPH Ultima Combo Pump 3/4" Hose Dura Port

The Johnson Pump 750GPH Ultima Combo Pump 3/4" Hose Dura Port is a compact, high-volume bilge pump engineered for serious boaters who demand reliability in unpredictable water conditions. Whether you're running a center console, cruiser, or work boat, this pump handles the critical job of removing water from the bilge before it becomes a safety issue. Built by Johnson Pump—a brand trusted by commercial fishing fleets and offshore operators—this unit delivers proven performance when it matters most.

Rated at 750 gallons per hour, this Ultima Combo Pump moves substantial water volume quickly, critical during heavy rain, rough seas, or when sealing integrity is compromised. The 3/4" hose connection accommodates standard marine plumbing and integrates seamlessly with existing through-hulls or manual backup systems. The Dura Port design enhances durability and reduces corrosion, extending service life in saltwater and freshwater environments alike. At just 1.1 pounds with compact dimensions of 7 x 4 x 7 inches, installation in tight engine compartments is straightforward, and the lightweight profile doesn't strain 12V or 24V electrical systems.

This pump is ideal for vessel owners seeking a secondary automatic bilge solution or as a primary pump for smaller to mid-sized hulls. Commercial operators, charter captains, and weekend anglers benefit from the fast response time and consistent flow rate that prevents water accumulation below decks. Installation requires basic marine wiring and hose compatibility—ensure your 12V or 24V system matches the pump's voltage specification, and verify 3/4" hose routing to your discharge through-hull. Pair it with a float switch for automatic operation and sleep soundly knowing your boat is protected.
