Attwood Tsunami MK2 Manual Bilge Pump

The Attwood Tsunami MK2 series is a manual bilge pump family engineered to eliminate airlocks using the patented X-Air impeller, preventing the pump from running dry and improving reliability in freshwater applications. The non-automatic design is optimized for dependable manual bilge pumping and retrofit replacement, offering a 90° rotatable elbow outlet that allows full 360° orientation for flexible installation. Mk2 models provide improved protection against water ingress and electrolysis versus prior Mk1 models and maintain backward compatibility with Mk1 hole patterns and motor cartridges for easy upgrades. External mounting feet and an integrated outlet reduce installation effort, while the serviceable pump cartridge can be removed using one hand for quick maintenance in hard-to-reach areas. The series is available in multiple flow rates and voltage options to suit different boat bilge needs.
