Name a safety device that shuts the engine off if the operator is thrown from the proper operating position.

The safety device that is designed to shut the engine off if the operator is thrown from the proper operating position is commonly referred to as a safety kill switch. This device serves a crucial role in enhancing boating safety by preventing runaway boats in the event that the operator loses control or is ejected from their seat.

The safety kill switch is typically connected to the operator’s person through a lanyard or similar mechanism, ensuring that if the operator is unable to control the boat, such as in an accident or a sudden movement that causes ejection, the engine will cut off immediately. This rapid shutdown helps prevent potential accidents, allowing the boat to remain stationary and reducing the risk of injury to the operator or others on the water.

Although the terms "emergency ignition safety switch" and "automatic shut-off device" might seem similar, they do not specifically convey the same operational mechanics as a safety kill switch. A pressure-release valve, on the other hand, pertains to different safety mechanisms typically not related to the operation of the engine in relation to operator safety.
