What is the purpose of a kill switch lanyard on a boat with an outboard motor?

• A. To hold the engine in place.
• B. To measure engine RPM.
• C. To attach a lifebuoy.
• D. To shut off the engine if the operator falls overboard.

Answer: (D)

A kill switch lanyard is a safety tether that stops the engine if the operator falls overboard. It connects the ignition to your clothing or life jacket so that if you move away from the helm or are pulled into the water, the lanyard releases and cuts power to the engine, causing the boat to stop or shut down. This prevents the boat from continuing to run uncontrolled, which could hit you, others, or run the boat aground. It doesn’t hold the engine in place, measure RPM, or attach a lifebuoy. For best use, always attach it before starting and test that pulling the lanyard stops the engine, replacing wear or damage promptly.
