Whale Gulley IC Large Waste Water Outlet

The Whale Gulley IC Large Waste Water Outlet (model SG1982B) is an intelligent shower drain gulley engineered for modern marine sanitation systems. This single-outlet waste water drain features built-in electronic sensing that detects water flow and automatically triggers evacuation through a connected Gulper IC pump unit. The intelligent control design eliminates manual valve operation, making it an essential component for cruising sailboats, trawlers, and offshore fishing vessels where reliable galley and head drainage is critical to vessel habitability.

The Gulley IC operates on a straightforward but effective principle: when water enters the basin, an electrical signal is transmitted to the paired Gulper IC pump, which immediately begins evacuating the system. As water level drops, the signal ceases, but the pump continues running for an additional 15 seconds to ensure complete drainage and prevent backflow. This brief overrun cycle is particularly valuable in rough sea conditions where residual water movement could otherwise create siphon problems. The compact 8 x 7 x 12-inch footprint integrates cleanly into galley and head layouts without consuming excessive deck or cabin space. At 1.65 lbs, installation adds minimal weight to the system.

This outlet is designed specifically for crews who operate in extended offshore passages or coastal cruising where manual pumping creates constant workload. Weekend boaters exploring rivers and protected bays also benefit from the reliability and convenience of automatic drainage. The Whale Gulley IC Large Waste Water Outlet must be paired with a compatible Gulper IC pump unit—the two components are interdependent and cannot function independently. Verify pump availability and electrical integration before ordering. For marine sanitation systems demanding intelligent automation without complex plumbing modifications, this Whale drain system delivers practical, proven performance across diverse vessel types and cruising scenarios.
