Johnson Pump 33103 Low Boy Bilge Pump, 1250 GPH, 12 Volt

The Johnson Pump 33103 is a 1250 GPH low profile bilge pump built for boats where clearance beneath the bilge is tight, such as under inboard or I/O engine beds. Its low boy housing design keeps the overall height down, making it easier to mount and remove the pump in cramped spaces without cutting into surrounding structure. The pump uses a removable cartridge style construction, so the internal pump cartridge can be pulled for cleaning or servicing without disconnecting the plumbing or wiring, cutting down on maintenance time.

Constructed of plastic housing components, the 33103 runs on a 12 volt DC power source and moves up to 1250 gallons per hour, suited to keeping bilge areas clear of accumulated water. Each unit ships complete with both a straight elbow and a 90 degree smooth elbow, giving installers the flexibility to route the discharge hose in the direction that best fits the boat's bilge layout without sourcing separate fittings. The smooth bore of the included elbows is designed to maintain water flow and resist clogging from debris.

This pump is intended for boating and water-related use, including bilge water removal in routine operation and water emergencies. It is a direct fit wherever a Johnson Pump 33103 Low Boy 1250 GPH 12 volt bilge pump is called for.
