Jabsco PAR-Max 3 Shower Drain Pump 12V 3.5 GPM

The Jabsco PAR-Max 3 Shower Drain Pump 12V 3.5 GPM is purpose-built for recreational boaters and liveaboard mariners who demand reliable water system management without compromise. Whether you're running a saltwater charter, cruising coastal waters, or maintaining a cabin cruiser, this pump handles shower drainage and general galley pumping with the dependability that separates weekend warriors from serious seafarers. At 3.5 GPM, it delivers consistent flow without the noise or vibration that can drive crew crazy during otherwise peaceful anchorages.

Built on Jabsco's proven four-piston diaphragm-sealed design, the PAR-Max 3 operates as a self-priming pump that runs dry without damage—a critical feature when bilge or freshwater systems cycle irregularly during cruising. The snap-in swivel ports eliminate plumbing headaches and reduce vibration transmission to hull and cabin structures, keeping noise levels low when the pump cycles. Meeting both USCG and ISO 8846 marine electrical standards, this 12-volt unit provides the regulatory compliance and safety certification your vessel needs for insurance and inspection purposes.

Serious cruising anglers and liveaboards rely on the PAR-Max 3 to handle shower drain operations, washdown stations, and galley sump applications across displacement and planing hulls alike. Its compact footprint—7 x 5 x 13 inches—fits tight engine compartments and under-cabin installations where space is at a premium, while the 5.4-pound weight won't stress structural mounting points. Installation is straightforward on 12-volt DC systems common to most recreational vessels, making this pump ideal for new builds, retrofits, and replacement applications in sailboats, trawlers, and center consoles operating fresh, brackish, or coastal waters.
