Johnson Pump 33703 Low Boy Bilge Pump, 750 GPH, 12 Volt, Red

The Johnson Pump 33703 Low Boy Bilge Pump is a 750 GPH, 12 volt bilge pump built for boats where the bilge pump has to be mounted beneath an inboard or I/O engine. Its low-profile housing and removable cartridge design make it easy to mount and remove in tight bilge spaces where a standard-height pump will not fit or cannot be serviced without pulling other components. The pump body is molded in red plastic for easy visual identification against a dark bilge, and it comes with both a straight fitting and a 90 degree smooth elbow so it can be plumbed to match the discharge hose routing in the installation.

Because the cartridge assembly lifts out of the base without disconnecting the wiring or through-hull plumbing, routine cleaning and impeller/cartridge service can be done in place, which is a common pain point on pumps mounted in cramped under-engine bilge areas. At a rated flow of 750 gallons per hour and 12 volt operation, the 33703 is sized for automatic or manual bilge duty in small to mid-size recreational boats.
