The Garmin OnBoard™ engine cutoff system is designed to meet the ABYC A-33 standard regarding emergency engine/propulsion cut-off devices. When using this system, observe the following considerations:

• Power to the GOS™ 10 hub should be tied to engine ignition in a way that it is operational when the engines are running. If the Garmin OnBoard engine cutoff system is installed and not powered on when the engines are running, it is not compliant with the A-33 standard.
• When the engines and the Garmin OnBoard engine cutoff system are running, you must have an MOB tag with the Captain role assigned, paired, and connected.
