Tsunami MK2 T500 Manual Bilge Pump with Installation Kit – 500 GPH & 12VThis is a complete kit (includes a bilge pump) to install a manual bilge pump with a 3/4″ I.D. hose outlet. The Tsunami Mk2 is the only manual bilge pump that eliminates airlocks. This is done by the Patented X-Air Impeller, which ejects trapped air in the pump and pipework. Also, the Tsunami Mk2 is the most reliable manual bilge pump in freshwater applications, considering it has 40% better protection against water ingress and electrolysis vs. the Mk1 pump.Kit Includes:Attwood Tsunami Mk2 500 GPH PumpWasher / Non-Return Valve90-degree OutletStraight Outlet3/4″ x 5′ Pump Hose3/4″ Thru-hull fitting2-way on/off switch with bezel plateSnap-It hose clampsWire KitInstallation KitEasy Installation & Service:GPH (Gallons Per Hour): 500 GPH90 rotatable elbow outlet allows users to install the pump anywhere in a full 360 orientationBackward compatible hole pattern and motor cartridges of Tsunami Mk1 bilge and aerator pumpsExternal mounting feet and integrated outlets reduce time and effortService pump cartridges from hard-to-reach areas using only one handSpecifications:Rated Volts DC: 12VDCFuse Size: 3 AMPWire Length: (inch) 29″ / (mm) 735mmHose Diameter: (inch) 3/4″ and 1″*Caution: Bilge pump switches are not external ignition protected Specifications:Gallons Per Hour: 500 GPHOperation: Non-AutomaticOutlet Size: 3/4″ or 1″Type: ElectricVolts: 12vBox Dimensions: 6″H x 7″W x 9″L WT: 1.75 lbsUPC: 022697024213Quick Guide (pdf)
