This 12-volt cartridge motor drops into the existing pump housing to restore full pumping performance once the original motor cartridge wears out or fails, without requiring replacement of the entire bilge pump assembly. It is constructed of black plastic and is rated for a maximum flow rate of 12.5 gallons per minute, matching the output of the 750 GPH pump family it is designed for.\u003c\/p\u003e\u003cp\u003eAs a cartridge-style motor, the 28572 is designed for straightforward swap-in replacement: the worn cartridge is removed from the pump base and the new Johnson Pump 28572 cartridge is installed in its place, reconnecting to the existing wiring and pump housing. This design lets boat owners restore bilge pump performance quickly rather than re-plumbing a new pump. Before ordering, confirm that your existing pump is the 750 GPH model that accepts the 32702 cartridge, since cartridge motors are matched to specific pump housings and are not universally interchangeable across different GPH ratings.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Johnson Pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 28572\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Model Number:\u003c\/strong\u003e 3001.3483\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Cartridge Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With:\u003c\/strong\u003e 750 GPH Bilge Pump, Model 32702\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12 Volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Flow Rate:\u003c\/strong\u003e 12.5 Gallons Per Minute\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Source:\u003c\/strong\u003e Corded Electric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.69 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 7.5 inches (L) x 6 inches (W) x 3 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 729321285728\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e750 GPH Bilge Pump, Model 32702\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat pump does the Johnson Pump 28572 fit?\u003c\/strong\u003e The 28572 is the cartridge motor for the 750 GPH bilge pump, Model 32702, and is designed to replace the motor cartridge in that specific pump housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a full pump or just the motor?\u003c\/strong\u003e This is the replacement cartridge motor only, not a complete bilge pump.
