Attwood Tsunami MK2 T500 12V Manual Bilge Pump Kit

The Attwood Tsunami MK2 T500 Manual Bilge Pump (500 GPH, 12V) is the only manual bilge pump on the market that eliminates airlocks. It is designed for boaters who want a reliable manual bilge pump backed by the same patented airlock-eliminating technology as Attwood's automatic Sahara line.

A patented X-Air impeller ejects trapped air from the pump and pipework, delivering the most reliable manual bilge pump performance in freshwater applications with 40% better protection against water ingress and electrolysis than the previous MK1 pump. A 90-degree rotatable elbow outlet allows installation in a full 360-degree orientation, and the pump remains backward compatible with the hole pattern and motor cartridges of Tsunami MK1 bilge and aerator pumps.
