Attwood Sahara MK2 Automatic Bilge Pump, 12V, 1200 GPH

The Attwood Sahara MK2 is a 12-volt automatic bilge pump rated at 1200 GPH, built for boaters who need dependable, low-maintenance water removal in a compact housing. It uses a patented X-Air impeller that clears trapped air from the pump chamber, eliminating the air-lock stalling that plagues many bilge pumps after periods of low water or dry running. Smart buoyancy-based automatic switching (SteadySwitch technology) starts and stops the pump based on water level without a separate float switch, which reduces wiring complexity and helps conserve battery power when the bilge is dry.

The housing and impeller assembly are molded from durable plastic in a white and blue finish, and the outlet is a 360-degree rotatable elbow design so the discharge can be aimed in any direction to suit the mounting location; both a 90-degree elbow outlet and a straight outlet are included so the pump can be plumbed either way. 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 corners of a bilge. At 12 volts DC and a maximum lifting height of 10.8 feet, the Sahara MK2 is sized for typical small to mid-size boat bilges, sumps, and livewells where automatic, unattended pump-out is needed.
