The Attwood Sahara Mk2 is the ONLY automatic bilge pump that eliminates air locks. What makes the Sahara Mk2 Automatic Bilge Pump 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 Sahara Mk2 the most reliable automatic bilge pump in freshwater and saltwater applications. The Sahara Mk2 is also the easiest automatic bilge pump to install and service.
