Attwood Tsunami MK2 T800 12V Manual Bilge Pump

The Attwood Tsunami MK2 is the only manual bilge pump that eliminates airlocks, using a patented X-Air Impeller that ejects trapped air from the pump and pipework rather than letting it stall the flow.

It's also the most reliable manual bilge pump in freshwater applications, with 40% better protection against water ingress and electrolysis compared to the earlier Mk1 pump.

A 90-degree rotatable elbow outlet lets it install in any orientation across a full 360 degrees, and it's backward compatible with the hole pattern and motor cartridges of Tsunami Mk1 bilge and aerator pumps. External mounting feet and an integrated outlet cut install time, and cartridges service from hard-to-reach spots using just one hand. Rated 800 GPH at 12V. Browse more bilge pumps.
