Johnson Pump 24V Aqua Jet WD 5.2 Washdown Kit (64534-24)

The Johnson Pump 5.2 GPM Aqua Jet Washdown Pump Kit with Hose - 24V  64534-24 is a complete, professional-grade washdown solution designed for vessels operating on 24V electrical systems. This all-in-one kit features the high-capacity 5.2 GPM Aqua Jet WD pump, delivering the volume and pressure required to remove stubborn mud, salt, and fish scales from decks and anchors with ease.

High-Volume 5-Chamber Performance

At the heart of this kit is a 5-chamber diaphragm pump that provides a significantly smoother and quieter flow than traditional 3-chamber models. The higher 24V efficiency allows for consistent, high-pressure cleaning (up to 70 PSI) with a lower amperage draw, making it ideal for larger yachts, commercial fishing boats, and workboats.

Key Features:

• Complete Washdown System: Includes the 24V pump, a PUMProtector™ intake strainer, a high-pressure spray nozzle, a 25' (7.5m) coiled hose, and bulk-head fittings.

• 5.2 GPM Flow Rate: High-capacity output ensures you have enough water volume to wash down large deck areas quickly.

• Whisper-Quiet Operation: The 5-chamber design minimizes pulsation and "water hammer" in the plumbing, protecting your fittings and reducing noise.

• 70 PSI Pressure Switch: Heavy-duty integrated switch automatically starts the pump when you pull the nozzle trigger and stops it when released.

• Self-Priming & Dry-Run Safe: Capable of priming up to 7 feet (2.1m) and can run dry for short periods without damaging the internal diaphragms.

• Corrosion Resistant: Features a powder-coated motor and seamless shell to withstand the harsh marine environment.

• Easy Installation: Includes quick-connect ports and a comprehensive hardware kit to get your washdown station running immediately.

Summary for the User

This kit is the ideal choice for larger vessels with 24V electrical systems that require a robust, long-lasting washdown solution. Its ability to handle both fresh and salt water makes it highly versatile for offshore fishing or general maintenance.

Why Choose the 24V Aqua Jet 5.2 Kit?

The Johnson Pump 5.2 GPM Aqua Jet Washdown Pump Kit with Hose - 24V  64534-24 is the ultimate upgrade for 24V vessels. By purchasing the kit rather than individual components, you ensure that every part—from the strainer to the spray nozzle—is perfectly matched to the pump’s high-pressure output. Its reliability and high flow rate make it the preferred choice for owners who need "industrial strength" cleaning power.

Installation Pro-Tip:

When mounting the pump on a 24V system, use 14 AWG tinned marine wire for runs up to 20 feet. Since 24V systems are more efficient regarding voltage drop than 12V systems, you can maintain peak 70 PSI performance even with longer wire runs, but always ensure connections are sealed with heat-shrink tubing to prevent corrosion.
