Most PWC and powerboats come equipped by the manufacturer with an important device called an emergency engine cut-off switch. This is a safety device that is designed to shut off the engine if the operator is thrown from the proper operating position.
A lanyard is attached to the switch and the operator's wrist or personal flotation device (PFD). The switch shuts off the engine if the operator falls off the PWC or out of the powerboat. If your vessel does not come equipped with an engine cut-off switch, you should have one installed.
It is illegal to ride your PWC without attaching the lanyard properly between the switch and yourself.
