Johnson Pump Proline Bilge Pump - 500 GPH

The Johnson Pump Proline Bilge Pump – 500 GPH is the workhorse every serious boater needs in the engine compartment. Whether you're running a center console, cruiser, or fishing boat, water intrusion happens—rain, splash-back, and normal condensation accumulate faster than you'd expect. This pump moves water out reliably before it becomes a problem, and the DuraPorts design means it handles the job day after day without corrosion stealing your peace of mind. If you spend real time on the water, a dependable bilge pump isn't optional; it's insurance.

Built to Johnson Pump's proven standard, the Proline delivers 525 GPH at 3 feet of head and 630 GPH straight discharge on a 13.6V system—that's capacity you can count on in real conditions, not just bench ratings. The pump draws only 2.5 amps and runs behind a standard 5A fuse, so it integrates into existing electrical without heavy modifications. The 3/4-inch port connection fits most factory and aftermarket through-hulls, and the DuraPorts construction resists saltwater corrosion better than older designs. Compact dimensions (6 x 4 x 7 inches) and modest weight (0.85 lbs) mean it fits into tight bilge spaces without fighting for room.

Recreational anglers, weekend cruisers, and professional captains alike rely on the Proline when stock pumps fail or when upgrading aging systems. It's especially valuable if you trailer your boat regularly or leave it moored in wet conditions—the higher GPH rating handles unexpected water faster than undersized alternatives. Installation is straightforward for anyone comfortable with basic marine wiring; most boatyards can have it running within an hour. The Proline has earned its reputation through years of consistent performance in freshwater and saltwater fleets, making it the sensible choice for anyone unwilling to bet their boat on a questionable pump.
