What will you do when you find yourself facing an emergency such as a man overboard or a barrier in the path of your boat? Each second makes a huge difference. Equip your boat with the cut-off switch from Siera. It comes with a lanyard that you can pull to switch off the ignition. This safety feature can be found in many new boats, but is a necessity that needs to be installed in older ones.

  • Kills ignition with a pull of the lanyard
  • Prevents run away of boats
  • Stops the boat’s engine
