ATTWOOD TSUNAMI MK2 500 MANUAL BILGE PUMP 12 V

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. This breakthrough technology makes Tsunami Mk2 the most reliable manual bilge pump in freshwater applications.
