The Johnson Pump 1250 GPH Ultima Combo Pump offers reliable automatic bilge pumping for marine applications, combining proven JPM Cartridge Bilge Pump technology with the advanced Ultima Switch for effortless operation. The integrated electronic switch employs patented Mirus field effect detector cells, which generate micro-electrical fields to accurately sense water levels in the bilge. This intelligent detection automatically activates or deactivates the pump, ensuring efficient water management without manual intervention. Designed for durability and ease of maintenance, the pump features a water-cooled motor that extends service intervals and a compact all-in-one motor and impeller unit with a stainless steel shaft for corrosion resistance. The thermoplastic pump body enhances durability while maintaining lightweight performance.

Installation is straightforward, with no tools required for routine maintenance, allowing for quick disassembly and reassembly while leaving the casing attached to the boat and hoses. The pumps come equipped with Dura-Port discharge ports for the 500 GPH, 750 GPH, and 1000 GPH models, which help eliminate stress cracking caused by over-tightening hose clamps. Each pump includes both straight and 90-degree smooth elbows and a removable check valve, providing versatile installation options. These pumps meet ISO 8849 marine standards and are CE-approved for safety and reliability.
