Johnson Pump 3.5 Aqua Jet Washdown 12V - 10-13399-03

Johnson Pump Aqua Jet WD 3.5 Washdown Pump | 12V (10-13399-03)

The Johnson Pump 3.5 Aqua Jet Washdown 12V 10-13399-03 is a high-pressure, 5-chamber diaphragm pump designed specifically for demanding washdown applications. Whether you are rinsing salt spray from your deck, cleaning mud off an anchor, or washing down a fish box, this pump provides the consistent power and pressure needed for a thorough clean.

Smooth and Quiet Cleaning Power

Unlike traditional 3-chamber pumps that "pulsate" and vibrate, the Aqua Jet WD 3.5 utilizes a 5-chamber design. This provides a significantly smoother flow and quieter operation. The integrated pressure switch is set to 70 PSI, ensuring a powerful jet of water that activates automatically when you pull the spray nozzle trigger and shuts off immediately when you release it.

Key Features:

• 5-Chamber Construction: Delivers a smooth, pulse-free flow that is gentler on your plumbing and much quieter during use.

• 70 PSI Pressure Switch: High-pressure shut-off calibrated for heavy-duty cleaning and effective debris removal.

• Self-Priming: The pump can prime itself up to 7 feet (2.1m), allowing for flexible mounting locations above the waterline.

• Dry-Run Capability: The heavy-duty diaphragm and valve design can run dry for short periods without sustaining damage.

• Durable Motor: Features a high-torque motor with a seamless shell and powder-coated finish for superior corrosion resistance in marine environments.

• Quick-Connect Ports: Includes O-ring sealed ports (hose barb and threaded) for easy installation, maintenance, and winterization.

• Ignition Protected: Meets ISO 8846 and USCG standards, making it safe for installation in engine compartments.

Why Choose the Aqua Jet WD 3.5?

The Johnson Pump 3.5 Aqua Jet Washdown 12V 10-13399-03 is the industry standard for mid-sized center consoles and cruisers. It strikes the perfect balance between manageable power draw and effective cleaning pressure. Its 5-chamber design is not only quieter but also reduces the "hammering" effect in the hoses, which extends the life of your washdown fittings and spray nozzles.

Installation Pro-Tip:

To protect your investment, always install the PUMProtector™ intake strainer (sold separately or as part of a kit) on the inlet side of the pump. This prevents sand, shell fragments, and seaweed from entering the pump chambers and fouling the valves.
