Johnson Pump Aqua Jet 5.2 GPM Washdown & 550 Livewell Kit – 64634

The Johnson Pump Aqua Jet 5.2 GPM Washdown/550 Livewell Kit (64634) is a versatile and powerful self-priming pump system built to deliver dependable washdown and livewell circulation performance on boats of all sizes. Featuring Johnson’s proven Aqua Jet technology, this kit combines rugged construction and quiet operation with a robust 5.2 gallons per minute (GPM) performance—perfect for deck washdowns, livewell circulation, baitwell aeration, or freshwater transfer tasks.

Designed as a complete kit, the 64634 Aqua Jet system includes a pump, mounting hardware, tubing, and all necessary fittings for straightforward installation. Whether you’re rinsing away salt, mud, and fish scales after a long day on the water, or keeping bait and catch healthy with steady livewell flow, this system delivers consistent, reliable performance you can count on.

Constructed with corrosion-resistant materials and engineered for effortless self-priming operation, the Aqua Jet kit is suitable for both freshwater and saltwater environments. Its compact footprint and quiet running make it ideal for center consoles, fishing boats, pontoons, and larger vessels equipped with washdown or livewell circuits.

Key Performance Features

• High-Pressure Wash Down: The Aqua Jet 5.2 pump delivers a powerful 70 PSI (5 bar) of pressure, making it ideal for blasting away mud, sand, and salt from decks and anchors.

• Dual-Port Livewell Pump: Includes a 550 GPH Twin Port aerator pump. The twin-port design allows one intake to feed both the livewell and the washdown pump simultaneously, simplifying your through-hull plumbing.

• Quiet & Smooth Operation: The washdown pump utilizes a five-chamber diaphragm design, which significantly reduces noise and water pulsation compared to standard three-chamber pumps.

• Automatic Sensing: Features an integrated pressure switch that automatically turns the washdown motor on and off when you pull the trigger on the spray nozzle.

• Durable Build: Both pumps are ignition-protected (ISO 8846) and designed to withstand the harsh marine environment. The washdown pump can even run dry without damage.
