Attwood Sahara MK2 Automatic Bilge Pump, 12V, 800 GPH

The Attwood Sahara MK2 is a fully automatic 12-volt bilge pump rated at 800 gallons per hour, built for continuous duty in the bilge of boats where reliable water removal is critical to keeping the vessel afloat and dry. The pump uses a patented X-Air impeller design that clears trapped air from the pump chamber, preventing the air-lock condition that causes many bilge pumps to run dry without moving water. Attwood's SteadySwitch technology governs the automatic on/off cycling with smart buoyancy control, so the pump activates only when needed and draws minimal current from the battery between cycles, an important factor for boats left unattended at a dock or mooring.

The outlet housing rotates a full 360 degrees, and the pump ships with both an elbow and a straight outlet fitting so it can be plumbed to match the discharge hose routing in a wide range of bilge layouts. A one-hand cartridge release lets the impeller cartridge be pulled for cleaning or servicing without tools, which matters in the tight, hard-to-reach spaces where bilge pumps are typically mounted. The housing and components are molded plastic in a white and blue finish, and the pump runs on a 12-volt DC electrical system. Included in the box are the pump unit, mounting instructions, a washer, a non-return valve (NRV) to prevent backflow through the discharge line, and both the 90 degree and straight outlet fittings.
