Johnson Pump Aqua Jet WPS 2.9 GPM – 12V – NPT – 2.8 Bar – 10-13405-103
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.

Installation Tip
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.
