Attwood Sahara MK2 Automatic Bilge Pump, 12 Volt, 500 GPH

The Attwood Sahara MK2 Automatic Bilge Pump is a 12 volt, 500 GPH DC bilge pump built for automatic water removal in boat bilges. It uses a patented X-Air Impeller to clear trapped air and keep pumping reliably even when air pockets would stall a standard impeller, and SteadySwitch technology provides smart buoyancy-based control that activates the pump only when needed to minimize battery drain. The pump has a maximum flow rate of 8.33 gallons per minute and a maximum lifting height of 7.5 feet, giving it enough head pressure to move water up and out of typical bilge locations.

Installation and servicing are simplified for hassle-free setup: the pump includes a one-hand cartridge release so the motor cartridge can be pulled and serviced without removing the base from the hull, and a 360 degree rotatable outlet lets the discharge elbow be aimed to fit the mounting orientation in the bilge. Both a 90 degree elbow outlet and a straight outlet are supplied so it can be plumbed either way. The housing is built of plastic in a white and blue finish, and the unit ships complete with the pump, instructions, a washer, and a non-return valve (NRV) to help prevent backflow into the bilge. It is designed for general boating use as an automatic bilge pump on 12 volt DC electrical systems.
