The Jabsco Par-Max 2 is a 24V DC freshwater delivery pump with a plastic housing that protects the motor from corrosion. A sealed pressure switch runs it on demand, and a bypass module is built in to reduce cycling and smooth the flow. It is self-priming, can run dry without damage, and uses quick connect ports with 1/2" hosebarb fittings. Maximum current is 3.0 amps, and the rated pressure is 35 PSI.

Our take

Run-dry tolerance and self-priming mean this 24V Par-Max 2 is not harmed by an empty tank. The integrated bypass module reduces cycling, giving smoother flow at the tap, and the sealed pressure switch handles on-demand operation.

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.
