Johnson Pump Ultima Combo Automatic Bilge Pump 07903-00, 1000 GPH, 12 Volt

The Johnson Pump Ultima Combo Automatic Bilge Pump (07903-00) is a 12 volt, 1000 gallon-per-hour bilge pump built for automatic water removal in boats. It combines the pump body with an integrated electronic float switch in a single cartridge unit, so the pump activates automatically without a separately wired mechanical switch. The cartridge design is a key feature of the Ultima Combo: the motor element can be pulled and replaced as a self-contained cartridge, so the pump base and plumbing do not need to be disturbed to service the motor.

The housing is molded from black plastic for corrosion resistance in a wet bilge environment. The pump moves up to 1000 gallons per hour and can lift water up to 3 feet of vertical head, and it runs on 12 volt DC power common to marine electrical systems. Overall product dimensions are 12 inches long by 11 inches wide by 12 inches high, and the unit weighs 1.1 pounds. This is a universal-fit automatic bilge pump suited to a wide range of boats and bilge compartments rather than a single specific make or model.
