Attwood Tsunami MK2 Manual Bilge Pump - T1200 - 1200 GPH & 12V

The Attwood Tsunami MK2 Manual Bilge Pump T1200 is a marine safety essential engineered to eliminate the single biggest failure mode in manual bilge pumping: airlocks. Using Attwood's patented X-Air impeller technology, this 1200 GPH pump actively ejects trapped air from both the pump chamber and connected pipework during operation, ensuring consistent priming and reliable water evacuation when you need it most. Unlike conventional manual bilge pumps that lose effectiveness as air pockets accumulate, the Tsunami MK2 maintains full pumping capacity throughout extended use cycles.

The MK2 generation delivers 40% better corrosion and electrolysis resistance compared to its MK1 predecessor, a critical advantage in saltwater and brackish environments where galvanic attack degrades standard materials. The pump's 1200 GPH capacity handles serious water ingress quickly, whether from a through-hull failure, heavy seas, or engine-room flooding. Dual-voltage compatibility (12V operation) allows integration with standard marine electrical systems. Compact dimensions and lightweight construction (1.25 lbs) simplify installation in tight bilge compartments, while the reinforced internal design tolerates both freshwater and saltwater service without sacrificing durability.

This pump serves offshore fishing vessels, cruising sailboats, commercial work boats, and any operator who requires reliable redundant bilge capacity. Weekend anglers running coastal waters benefit equally; a manual bilge pump with proven airlock elimination provides genuine backup if the electric system fails during a critical moment. The Tsunami MK2 represents the evolution of manual pumping technology—solving the air-trapping problem that has plagued mechanical bilge systems for decades. Installation and service access are straightforward, critical factors when every moment counts in a water emergency.
