Engine Cut-Off Switch (ECOS)
If the vessel is equipped with a lanyard-type ECOS, the lanyard must be attached to person, clothing, or PFD of the operator at all times when a PWC is underway and at greater than headway speed for all other motorboats under 26 feet in length other than a PWC. The operator of the vessel is also responsible for verifying that the ECOS system is operating.
