Johnson Pump Aqua Void Automatic 800 GPH Bilge Pump - 12V

The Johnson Pump Aqua Void Automatic 800 GPH Bilge Pump - 12V is the workhorse bilge system every serious angler and boater should trust in the engine room. Water intrusion happens—whether from rough seas, a stray wave at the dock, or condensation buildup on extended trips—and when it does, you need a pump that responds automatically without thought or delay. This compact, lightweight unit delivers 800 gallons per hour of evacuation capacity, making it ideal for center consoles, cruisers, fishing boats, and any vessel where reliable automatic dewatering is non-negotiable.

Built for 12-volt DC systems—the standard across most recreational vessels—the Aqua Void operates automatically via a float switch that triggers pump engagement the moment bilge water reaches a preset level. Once water recedes below that threshold, the pump shuts down, conserving battery power and eliminating constant cycling that stresses electrical systems. The 800 GPH flow rate is sufficient to handle moderate water ingress and condensation accumulation on boats up to roughly 30 feet, making it a practical choice for both saltwater and freshwater applications where corrosion resistance and durability are paramount.

Installation works best in the lowest point of your bilge, typically aft of the engine compartment where gravity naturally pools water. The lightweight 1-pound form factor allows discreet mounting without consuming valuable space or requiring structural reinforcement. Whether you're running offshore tournaments, weekend cruising, or protecting a seasonal investment moored in humid conditions, the Johnson Pump Aqua Void Automatic 800 GPH Bilge Pump - 12V delivers the peace of mind that water will exit your hull faster than it entered.
