The Johnson Pump Aqua Jet WPS 2.9 GPM Water Pressure Pump System is a compact, intelligent freshwater pressure solution designed for boats, RVs, and mobile water systems requiring quiet operation and consistent pressure. Operating on 12V DC, this system delivers up to 2.9 gallons per minute at 2.8 bar (approximately 40 PSI), making it ideal for supplying water to sinks, showers, and small onboard appliances.
Featuring variable-speed diaphragm pump technology, the Aqua Jet WPS automatically adjusts pump speed based on water demand, providing smooth, pulse-free water flow while reducing noise, vibration, and power consumption. The integrated electronic pressure control eliminates the need for an accumulator tank, simplifying installation and reducing system complexity.
Built with marine-grade materials and corrosion-resistant components, the Aqua Jet WPS is engineered for long service life in harsh environments. NPT threaded ports ensure easy integration with standard plumbing systems, making this unit a versatile choice for both new installations and system upgrades.
Crankshaft Mount: Designed for direct mounting to the crankshaft pulley on various engine models (often found on Chevy, Chris Craft, and GMC engines).
Self-Priming: Provides excellent suction capability, ensuring immediate water flow to the engine's cooling system upon startup.
High-Speed Performance: Optimized for the high RPMs of a crankshaft drive, providing consistent cooling even at cruising speeds.
Body Material: Built with a rugged bronze body to resist corrosion in both fresh and saltwater environments.
Impeller: Features a high-quality flexible impeller that is easy to replace during routine seasonal maintenance.
F5B-9 Pump Assembly: The complete bronze pump housing and internal components.
Pre-installed Impeller: Typically includes a standard MC97 or Neoprene impeller.
Installation Ports: Features 5/8" FPT (Female Pipe Thread) ports for plumbing connections.

The Aqua Jet WPS 2.9 GPM combines intelligent pressure control, quiet performance, and simplified installation into a compact package. With smooth water delivery and reliable marine-grade construction, it’s an excellent solution for boaters and RV owners seeking residential-style water pressure without complexity.
When installing the F5B-9, ensure the torque arm (if applicable to your specific engine setup) is properly secured to prevent the pump body from rotating. It is also a best practice to lubricate the new impeller with glycerin (never petroleum-based grease) during replacement to prevent damage during the first few seconds of dry startup.
