Coast Guard Announces New Engine Cut-off Switch Law

According to a recent news release from the United States Coast Guard, operators of recreational vessels less than 26 feet in length will be required to use an engine cut-off switch (ECOS) and associated ECOS link (ECOSL) as of April 1, 2021, as the U.S. Coast Guard implements a law passed by Congress.

The ECOS and ECOSL prevent runaway vessels and the threats they pose. The ECOSL attaches the vessel operator to a switch that shuts off the engine if the operator is displaced from the helm. The ECOSL is usually a lanyard-style cord that attaches to an ECOS either in close proximity to the helm or on the outboard motor itself if the vessel is operated by a tiller. When enough tension is applied, the ECOSL disengages from the ECOS and the motor is automatically shut down. Wireless ECOS have recently been developed and are also approved for use. These devices use an electronic “fob” that is carried by the operator and senses when it is submerged in water, activating the ECOS and turning the engine off. Wireless devices are available on the aftermarket and are beginning to become available as manufacturer-installed options.

Each year, the Coast Guard receives reports of recreational vessel operators who fall off or are suddenly and unexpectedly thrown out of their boat. These events have led to injuries and deaths. During these incidents the boat continues to operate with no one in control of the vessel, leaving the operator stranded in the water as the boat continues on course, or the boat begins to circle the person in the water eventually striking them, often with the propeller. These dangerous runaway vessel situations put the ejected operator, other users of the waterway, marine law enforcement officers, and other first responders in serious danger.

Section 503 of the Coast Guard Authorization Act of 2018 required manufacturers of covered recreational vessels (less than 26 feet in length, with an engine capable of 115 lbs. or more of static thrust) to equip the vessel with an ECOS installed as of December 2019. Owners of recreational vessels produced after December 2019 are required to maintain the ECOS on their vessel in a serviceable condition. It is recommended that recreational vessel owners regularly check their existing ECOS system to ensure it works properly, following manufacturer’s instructions.

Section 8316 of the Elijah E. Cummings Coast Guard Authorization Act of 2020 requires individuals operating covered recreational vessels (less than 26 feet in length, with an engine capable of 115 lbs. or more of static thrust, which equates to about 3 horsepower or more) to use ECOS “links” while operating on plane or above displacement speed. Using the ECOSL is not required when the main helm is installed within an enclosed cabin. Common situations where ECOSL use would not be required include docking/trailering, trolling, and operating in no-wake zones.  

Seven states currently have ECOS use laws for recreational vessels, and 44 states have ECOS use laws for personal watercraft (PWC).
