Whale Gulper Grouper Mk3 12V Fishbox Pump 90-Deg Ports

The Whale Gulper Grouper Mk3 12V Fishbox Pump 90-Deg Ports is built to evacuate fish boxes and similar compartments where water may contain scales, bait residue, melting ice, and other typical debris. Its diaphragm pumping technology avoids the close-clearance impeller found in many macerator pumps and uses non-choke valves to move mixed waste more reliably.

Filterless operation reduces maintenance in dirty-water service, while self-priming capability allows the pump to be mounted away from the fish box in a drier, more accessible location. Model-specific port orientation helps installers route larger waste hoses through crowded onboard spaces.

Confirm voltage, circuit protection, hose sizes, pickup location, discharge destination, mounting position, and service access before installation. Keep large foreign objects out of the box, route hoses without sharp restrictions, and flush the pump with clean water after demanding service to help maintain dependable operation.
