Attwood Tsunami MK2 bilge pump.

Attwood Tsunami Mk2, the ONLY manual bilge pump that eliminates air locks. What makes Tsunami Mk2 so innovative is the patented X-Air™ Impeller. Its engineered performance forces air bubbles trapped in the hose and underside of the pump out of the pipework, so that the pump will not run dry and burn out. With single-hand pump cartridge release, easy access a pump located in a hard-toreach area of the boat’s hull. Industry’s best motor and shaft seals provides better protection against harmful corrosion that in any other instance could cause failure.
