The Attwood 56067 Tsunami T500 Mk2 Cartridge Bilge Pump is a 12V bilge pump built for reliable, hands-on bilge water removal. Designed with an X-Air™ anti-airlock impeller and a cartridge-style pump body, it’s made to help prevent dry running and simplify service access when space is limited.

Key Features

  • Patented X-Air™ impeller helps prevent air locking so the pump won’t run dry and burn out
  • 90° rotatable elbow outlet supports flexible mounting and a full 360° installation orientation
  • Single-hand cartridge release helps you access and service the pump when it’s in a hard-to-reach hull location
  • Exterior mounting feet help streamline installation by reducing the need to remove the basket during OEM production
  • Cartridge swap service: no pipe or hose removal is required to replace the cartridge
  • Industry-focused motor and shaft seal design helps protect against harmful corrosion that can lead to failure
  • Tricuspid check valve helps prevent backflow through the pump
  • Performance listed at 13.6V: with & without check valve (GPH ratings)

Product Compatibility

  • Boats and marine vessels with a 12V electrical system that require bilge water removal
  • Bilge pumping systems where cartridge-style service access is preferred for faster maintenance
