The Johnson Pump Ultima Combo Automatic Submersible Bilge Pump (1150 GPH, 12V) combines Johnson Pump's proven Cartridge Bilge Pump with the non-clogging electronic Ultima Switch for automatic operation. It is designed for boaters who want a compact, all-in-one motor/impeller unit that automatically activates and deactivates based on bilge water level.

The Ultima Switch uses patented Mirus field effect detector cells that produce micro-electrical fields to detect water level disruptions in the bilge, automatically running the pump as needed.
