Johnson Pump 32-47261-002 Ultima 1250 GPH Automatic Bilge Pump, 12V

The Johnson Pump 32-47261-002 is a 12-volt Ultima automatic bilge pump built to keep small to mid-size boats dry with minimal fuss. It moves up to 1250 gallons per hour on a straight discharge run, or 800 gallons per hour against a 3 foot head, giving it enough capacity for cockpit drains, bilge sumps, and general water removal duty. The pump has an integrated switch, so it activates automatically when water reaches its trigger level and shuts off once the bilge is clear, without a separate float switch wired into the circuit.

Wiring is reverse-protected, meaning the pump is designed to prevent damage from incorrect polarity during installation, which reduces the chance of a wiring mistake burning out the motor. Inside, a heavy duty motor drives a stainless steel shaft, while the outer body is molded from a tough thermoplastic that resists the corrosion and cracking that plague lower-grade bilge pumps exposed to saltwater and bilge chemicals. The pump draws 3 amps and is rated for a 5 amp fuse, and it discharges through a 1-1/8 inch or 1-1/4 inch connection, making it compatible with common bilge hose sizes without an adapter in many installations.

At 6 inches long, 3.2 inches wide, and 4.6 inches high, the 32-47261-002 fits into tight bilge spaces where larger pumps will not. It ships with the pump and an instruction manual, ready to wire in and mount.
