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.

Accidental ejections, such as falling overboard, are more likely to occur in:
• Low‑sided sport boats
• Bass boats
• High‑performance boats
Accidental ejections can also occur from:
• Poor operating practices
• Sitting on the seat or gunwale at planing speeds
• Standing at planing speeds
• Operating at planing speeds in shallow or obstacle‑infested waters
• Releasing your grip on the steering wheel
• Carelessness caused by consuming alcohol or drugs
• High‑speed boating maneuvers
The lanyard is a cord usually between 122 and 152 cm (4 and 5 ft) long when stretched out, with an element on one end made
to be inserted into the switch, and a snap on the other end for attaching to the operator. The lanyard is coiled to make its at‑rest
condition as short as possible to minimize the likelihood of lanyard entanglement with nearby objects. Its stretched‑out length is
made to minimize the likelihood of accidental activation should the operator choose to move around in an area close to the
operator's normal position. The operator can shorten the lanyard by wrapping the lanyard around his wrist, or by tying a knot in
the lanyard.
Activation of the lanyard stop switch will stop the engine immediately, but the boat will continue to coast for some distance,
depending upon its velocity. While the boat is coasting, it can cause injury to anyone in the boat's path as it would under power.
