The primary purpose of a kill switch on a boat is to stop the engine in case of an emergency. A kill switch, also referred to as a safety lanyard or engine cutoff switch, is designed to enhance the safety of the operator and passengers. When the operator is ejected from the boat or falls overboard, the kill switch cuts off power to the engine, preventing the boat from continuing to operate unchecked. This mechanism helps to prevent accidents that could occur if the boat were to run unattended.

This safety feature is particularly important in situations where an operator might lose control of the vessel, such as during rough weather or unexpected maneuvers. By immediately stopping the engine, the kill switch helps to protect not only the individual who has fallen off but also other nearby boaters and people in the water.

The other options do not accurately reflect the main function of the kill switch. While it may indirectly assist in preventing capsizing by stopping excessive acceleration, that is not its primary goal. Similarly, controlling speed is typically managed through throttle inputs rather than a kill switch. The kill switch does not serve as a signaling device for help; instead, it focuses on preventing runaway boat scenarios.
