Johnson Pump Aqua Jet 12V Washdown Pumps - Available in 3.5 GPM and 5.2 GPM

The Johnson Pump Aqua Jet series delivers reliable, self-priming washdown power for rinsing anchors, decks, gear, and catch aboard any boat. Built around a five-chamber diaphragm design, these 12V DC pumps run dry without damage, switch on automatically the moment the trigger nozzle opens, and shut off cleanly when it closes. Each pump ships ready to plumb in, with a PUMProtector inlet strainer to keep debris out of the pump head and a trigger spray nozzle to get you rinsing right away. Choose the 3.5 GPM Aqua Jet for compact washdown stations and lighter-duty rinsing, or step up to the 5.2 GPM Aqua Jet when you need faster flow for larger deck areas, bigger anchor lockers, or higher-demand washdown tasks.

Sizes & Options

Both pumps in this line share the same mounting footprint, connection sizing, and included accessories, so the choice comes down to flow rate. Pick the 3.5 GPM Aqua Jet (10-13399-03) for standard washdown duty where lower current draw and quieter operation matter most. Pick the 5.2 GPM Aqua Jet (10-13407-07) when you want higher output for faster rinsing or longer hose runs. If you are replacing an existing pump, match the flow rate to your current unit or size up if washdown speed has been a complaint.
