The Frank LoBiondo Coast Guard Authorization Act of 2018 contains requirements that affect all recreational boats less than 26 feet capable of producing more than 115 pounds of thrust to have an engine cutoff device per ABYC A-33:July 2018 Emergency Engine/Propulsion Cut-off Devices.
The compliance date is December 4, 2019 (USCG enforcement on boats with HINs ending A020). These requirements took effect in the middle of model year 2020. Most boatbuilders already provide a cutoff device, and engine and controls manufacturers have products available that comply with A-33. As a member of ABYC, you have access to the standard via the online library.
The requirements are published in the United States Code (USC) Title 46 Subtitle II Part B Chapter 43 § 4312. The USC is different from the Code of Federal Regulations (CFR) where most of boat manufacturer legal requirements are found.
