The engine cut-off switch only helps when the operator uses it
A working lanyard or wireless engine cut-off device can stop propulsion if the operator is thrown away from the controls. Test it and connect it before getting underway.

What you need to know
Why the device matters
The U.S. Coast Guard explains that an engine cut-off switch can shut down the engine when the operator is separated from the operating area. Stopping propulsion may reduce the risk from an uncontrolled boat and spinning propeller.
Make it part of departure
A lanyard left wrapped around the control does not protect the operator. Attach it as directed, or confirm that the approved wireless device is paired and active before leaving idle speed.
- Inspect the clip, cord and switch for damage
- Test operation according to the manufacturer instructions
- Keep an appropriate replacement aboard
- Explain restart procedures to another capable passenger
Check the rules for the boat
Equipment and use requirements can depend on the vessel and how it is operated. Review current Coast Guard guidance and applicable state rules rather than relying on what a previous owner did.
