Johnson Pumps 10-25013-03 Aqua Jet WD II 3.5 GPM 12V Washdown Pump with Nozzle

The Johnson Pumps Aqua Jet WD II is a 12V DC marine washdown pump delivering 3.5 GPM flow at up to 72 PSI pressure cut-off — ideal for deck wash-down duties on small to medium-sized recreational and commercial vessels. Its five-chamber positive displacement diaphragm design runs quietly and virtually pulsation-free, making it a reliable onboard cleaning solution.

An integrated automatic pressure switch activates the pump when the included nozzle is opened and shuts it off when closed, providing hands-free convenience and protecting the pump from dry running. The self-priming design ensures easy startup without manual priming.
