Whale Marine Supersub 500 Non-Automatic Bilge Pump, 12 Volt, 500 GPH, Low Profile

The Whale Marine Supersub 500 is a 12 volt, non-automatic bilge pump built into a narrow, low profile housing designed to fit tight bilge spaces where a taller pump will not sit flush. Rated to move up to 500 gallons per hour, it is intended for clearing bilge water from small to mid-size boats and keeping the bilge dry during normal operation. The housing is molded from durable plastic in a black finish, chosen for its resistance to constant exposure to bilge water and marine moisture.

Because this is a non-automatic model, it is switched on and off manually or through a separate control rather than an internal float switch, giving the operator direct control over when the pump runs. Its low profile, narrow footprint (11.18 inches long by 6.14 inches wide by 2.67 inches high) makes it a straightforward fit for compact bilge sumps and shallow bilge areas where clearance is limited. As a single-unit pump, installation follows standard 12 volt bilge pump wiring and thru-hull discharge practice.

The Supersub 500 is built for boat owners who want a compact, reliable manual bilge pump for routine water removal, backup dewatering, or as a dedicated pump wired to a separate switch panel rather than an automatic float-activated circuit.
