The Nuova Rade 43693 Emergency Stop Key for OMC / Johnson-Evinrude Marine Outboards is complemented by a braided bungee cord with a snap hook to connect with the passenger of the boat. When a person falls overboard, a stretched cable pulls the pin out of the motor housing, opening the net, stopping the motor and stopping the boat's movement. The device is made of high-quality plastic, which guarantees its durability and excellent performance.
