Attwood Tsunami Mk2 T800 12V Bilge Pump, 800 GPH, Replaces 4608-7

The Attwood Tsunami Mk2 T800 is a 12 volt DC bilge pump rated for 800 gallons per hour, built for reliable water removal in boats operating in freshwater conditions. It uses a patented X-Air Impeller that clears trapped air pockets so the pump keeps moving water instead of losing prime, a common failure point in lesser bilge pumps. The pump is designed for quick installation and easy service, with a one-hand cartridge release that lets you pull the impeller cartridge for cleaning or replacement without tools or awkward reach into tight bilge compartments. The outlet is a 360 degree rotatable elbow design, so the discharge can be aimed in any direction to match your hose routing, and the pump ships with both a 90 degree elbow outlet and a straight outlet fitting to fit different mounting layouts. Construction is durable plastic in a white and blue housing, sized to fit compactly into standard bilge mounting locations. In the box you get the pump unit, mounting instructions, a washer, a non-return valve (NRV) to prevent backflow when the pump shuts off, the 90 degree outlet, and the straight outlet. This is a direct replacement for the Attwood 4608-7 12V T800 pump, so it drops into the same mounting footprint and plumbing as that earlier part number.
