My boat has a toggle kill switch beneath the throttle. The switch is currently toggled to the up position, so obviously the down position kills the boat. Should I have a lanyard or something connected to this? I don't really understand the physics of the setup. I mean, if I attached the lanyard to myself and happened to fly out of the boat, what forces the toggle switch to the down position. Is the lanyard hook up thick enough to wedge it to the down position?
