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 & ServiceGPH (Gallons Per Hour): 50090° 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 outlet reduces time and effortService pump cartridges from hard-to-reach areas using only one handSpecifications:Rated Volts DC: 12VFuse Size: 3 AmpWire Length: (inch) 29" / (mm) 735Hose Diameter: (inch) 3/4" and 1"*Caution: Bilge pump switches are not external ignition protected
