Johnson Pump 102500501 Aqua Jet II Duo, 10.4 gpm, 12V, 40psi

A high-capacity water pressure system, designed for larger boats and demanding freshwater applications. Combining two Aqua Jet II pumps with an integrated accumulator tank, this powerhouse delivers an impressive 10.4 GPM (40 L/min) of flow, ensuring steady, home-like water pressure across multiple taps, showers, and galley sinks-even when several outlets are in use at once. Each pump’s five-chamber diaphragm design guarantees smooth, vibration-free operation, reducing noise and eliminating annoying pulsation for a more comfortable onboard experience. Built tough for harsh marine conditions. Features corrosion-resistant construction with advanced triple-layer protective coatings for long-lasting durability. Installation is simple thanks to the heavy-duty mounting bracket and 3/4" hose barb connections. The integrated accumulator minimizes pump cycling to extend system life. With dual pressure ratings: 41 psi on the primary pump and 30 psi on the secondary.
