The most reliable manual bilge pumps for freshwater vessels, the Attwood Tsunami MK2 Bilge Pumps help you enjoy your time on the water at ease! The Tsunami MK2 Bilge Pumps rely on patented X-Air Impeller systems that eject air in the pump and pipework making them the only manual bilge pumps to eliminate air locks and improve longevity by preventing burnout. The X-Air impellers couple with tricuspid check valves to aid in preventing water from backflowing through the pump. Additionally, they feature industry-leading motor and shaft seals to deliver improved protection against harmful corrosion that could cause failure.

Installing and maintaining Attwood Tsunami MK2 Bilge Pumps couldn’t be easier! Exterior mounting feet reduce the time and effort needed to install your new pump while flexible outlets and 90-degree rotatable elbows allow users to install the pump anywhere in a full 360-degree orientation. The pumps offer single-hand cartridge releases for increased convenience when trying to access a pump located in hard-to-reach areas of the boat’s hull. Available in multiple GPH ranges to accommodate a variety of vessels, the Attwood Tsunami MK2 Bilge Pumps are perfect for any boater looking for dependable safety equipment for their aquatic adventures!
