how does a boat kill switch work

How does a boat kill switch work? It works, as we’ve already mentioned, by way of linking the captain to the engine directly. If you move too far from the engine, such as in the examples above, the lanyard will disconnect – acting as a switch – to turn the engine off automatically.

The kill switch is attached to the helmsman, either physically or electronically. If the helmsman is thrown from the boat's controls, the connection between the helmsman and the kill switch is severed and the switch automatically turns the engine off, thereby immobilizing the propeller and the boat.
