Lanyard Stop Switch

A lanyard switch is designed to shut down the engine in the event the operator unexpectedly moves away from the helm, as
may happen in an accidental ejection. The lanyard is connected to the operator's personal flotation device or wrist.
A decal near the lanyard stop switch reminds the operator to attach the lanyard to his or her personal flotation device or wrist.
