TWIN PORT AERATOR PUMP 500 GPH 12V

MIA's Description

The Johnson Pump 48503 is a twin-port aerator pump designed for marine applications. It offers the convenience of using a single intake for both live well and raw water washdown pump duties. The pump features a tapered inlet that connects directly to a sea cock, with an upper outlet port for continuous flow to the live well. Its new high-pressure inlet seal can handle the pressures generated by high-speed pickups.
