Specifications

Pressure
41 psi

The Johnson Pump Aqua Jet is a 12 volt DC washdown pump rated at 2.9 GPM, with a cut off pressure of 41 PSI. It is self priming, with a maximum suction lift of 6.5 ft, and calls for a 10 amp fuse. An integrated pressure switch starts and stops the pump as the spray nozzle is opened and closed. It has built-in thermal protection, tolerates running dry, and is ignition protected to ISO 8846. A trigger nozzle, an inlet strainer and hose connector fittings are included.

Our take

The built-in pressure switch is the useful part here: the pump runs only while the trigger nozzle is open, so you don't need a separate switch at the pump. Dry-run tolerance also means a tank running out mid-wash won't harm it.

From our buying guide

Size a freshwater pump by the outlets that must run at once. Jabsco's rule of thumb is 1 GPM per outlet, and the listed flow is open flow, which falls as pressure rises.

Check before you buy:

  • The data sheet shows flow at pressure. One Shurflo gives 4.0 GPM at 0 psi and 2.0 GPM at 40 psi.
  • You have an inlet strainer, which Jabsco says is required in every freshwater pump installation.
  • An accumulator suits the pump. Jabsco says one cuts cycling on a pressure-switch system, and not to use its accumulators with variable-speed pumps.
