Whale Supersub 12V Low-Profile Automatic Bilge Pump

The Whale Supersub 12V Low-Profile Automatic Bilge Pump is an automatic electric bilge pump built to remove accumulating water without requiring the operator to switch the pump on manually each time. Its compact submersible construction allows installation low in the bilge where water naturally collects.

The pump's integrated automatic sensing and efficient motor support unattended bilge management when the vessel's electrical system is energized. The model's compact or low-profile geometry is especially useful in narrow bilge spaces where conventional upright pumps may not fit.

Confirm voltage, circuit protection, discharge-hose size, mounting position, automatic-sensor clearance, wiring route, and overboard discharge location before installation. Keep the inlet area clear of debris, use marine-grade electrical connections, and test automatic operation with water before relying on the pump. Find more in our bilge and water pumps.
