Johnson Pump Cartridge Combo 1000GPH Auto Bilge Pump w/Switch - 12V

The Johnson Pump Cartridge Combo 1000GPH Auto Bilge Pump with Switch (12V) is an essential safety system for any boater serious about keeping water out of the bilge. After years on the water, the reality is simple: bilge pump failure ends trips and risks vessels. This fully automatic, cartridge-based system eliminates manual operation—the pump activates when water reaches the float switch, then shuts down automatically once levels drop. Built for 12-volt systems common on center consoles, bay boats, and cruisers, this Johnson Pump combo delivers the reliability anglers and recreational boaters depend on in rough conditions or extended offshore runs.

The heart of this system is its non-clogging electronic float switch, which prevents false alarms from debris or silt common in real-world bilge environments. The pump itself is rated at 1000 GPH straight discharge (63 liters per minute at 13.6V), with reduced capacity of 800 GPH at 3-foot head pressure—a critical spec for understanding performance when pumping uphill or through through-hull fittings. The cartridge design means the pump can be serviced or replaced without removing the entire installation, saving time and frustration during maintenance. Compact dimensions of 7 x 5 x 7 inches allow installation in tight engine compartments without sacrificing intake or discharge flow.

This combo is ideal for anglers and boaters who spend full days on the water in variable sea states, where automatic bilge operation provides peace of mind during long runs or when tied up overnight. Whether you're operating a center console in the Gulf, a tournament bass boat on inland reservoirs, or a cruiser in coastal waters, the Johnson Pump's proven cartridge system delivers consistent performance. Installation requires a 12-volt power source and a through-hull fitting; check your existing bilge outlet sizing and ensure adequate discharge capacity before purchase. For anyone upgrading from manual-only systems or replacing failed pumps, this Johnson offering combines proven engineering with the automatic reliability that modern boaters demand.
