Jabsco Par-Max HD5 12V 5-GPM 40-PSI Water Pump

The Jabsco Par-Max HD5 12V Water Pump (part P501J-115S-3A) moves about 5 gallons per minute with a 40 psi shutoff. Five gallons a minute is enough to run a shower and a galley tap at the same time without a big pressure drop. The 40 psi setting keeps stress low on older hoses and fittings.

Flow and pressure work together: higher flow keeps several taps running, while higher pressure gives a stronger spray from each. This model favors flow, which suits busy boats with several people aboard. The integrated bypass module smooths flow and can reduce the need for a large accumulator.

The heavy duty motor and cast aluminum housing are built for long life. Install a strainer on the inlet and keep the quick-connect ports clean when servicing. In cold climates, drain the pump or use non-toxic potable water antifreeze for winter storage. The 60 psi HD5 and other pumps are in our fresh water and washdown pumps.
