FEATURES Body: Impeller: Seal: Ports: Motor: Dimensions: Weight: Bronze Jabsco Nitrile compound Lip Type 1/2" Internal Pipe Threads 1" External Hose Barb Adapter for 3/4" External Garden Hose Thread included Permanent magnet type, fully enclosed, stainless steel shaft, ball type shaft bearing, has adequate torque to reverse the pump 3" (76mm) high, 6-7/8" (175mm) long, 4-3/4" (120mm) wide 6 lb (2.7 kg) Model Voltage Motor meets USCG Electrical Standard 183.410 and ISO 8846 MARINE for IGNITION PROTECTION on gasoline powered vessels. Explosion Hazard. Do not pump gasoline, solvents, thinners or other flammable liquids. To do so can cause an explosion resulting in injury or death. Explosion Hazard. Do not operate with rivets removed from motor case. Explosion resulting in personal injury, death or property damage can occur. Case openings must be sealed to avoid explosion and maintain ignition protected rating. APPLICATION Use for bilge pumping, livewell circulation, washdown and general pumping requirements. For intermittent duty, motor may be reversed to empty bait tank. Pump has a dry prime suction lift of about 6 feet (2m) and a lift to 20 feet (6m) when primed. BE SURE SUcTiON LINES ARE AIRTIGHT. INSTALLATION The pump must be mounted in a dry location—the motor is not waterproof and must not be submerged. SELECTION OF A COOL VENTILATED location will generally extend pump motor life. The unit can be mounted in any desired position. It is best to mount so that water dripping from loose port connection will not wet the motor. The pump head may be rotated 180° on the motor to change the direction of flow. PLUMBING CONNECTIONS Pump ports have external 1" hose barb and internal 1/2" pipe threads. Also provided are two male port adapters to allow the attachment of 3/4" female garden hose fittings. Use hose that does not kink when bent and with sufficient wall thickness to prevent collapse when used on suction side of pump. Hoses should be routed so that some water will be retained in pump body to wet the impeller. Wetting the impeller aids in priming and extends impeller life. Use a strainer on the intake hose to stop trash and solids from going through the pump. All hoses must have airtight connections to enable faster priming.

ELECTRICAL CONNECTIONS Connect black wire to negative (-) terminal of battery. The orange wire should run to a properly sized (see electrical specifications) overload protected switch or circuit breaker, with a wire from switch or breaker to positive (+) terminal of battery. Electrical circuit must be independent of all other accessories. A reversing switch may be used to reverse the pump (JABSCO Part Number 18753-0652). Preferred motor rotation is clockwise looking at shaft end of motor. To prolong motor life, install pump so normal motor rotation is clockwise. Use proper wire size as...

MAINTENANCE Check wires and connections to be sure corrosion is not adding additional resistance to the motor circuit and causing a low voltage condition at the motor. Low voltage can inhibit motor from starting and cause fuse to blow. Full voltage should be available to prevent motor damage. NOTICE: If pump is idle for extended periods, the impeller may stick to the pump body, preventing motor rotation and causing blown fuses. To correct, remove end cover and impeller, clean body and impeller, then lubricate with water or small amounts of grease before assembly. If pump is to be in...
