Bypassing the System From a Chartplotter

One method to bypass the Garmin OnBoard™ engine cutoff system is by using a connected chartplotter.

NOTE: Bypassing the engine cutoff system using the chartplotter is possible only when the system has cut off the engines due to a man overboard event with a Captain tag, or when testing the system. This option is not available during normal operation.
Within 30 seconds after the system has cut off the engines, select one of these options on a connected chartplotter:
  • Select Yes in the message that reads Do you want to be able to restart the engine now?1

  • On an MOB screen, select Disable Cutoff1.

  • Select Settings menu > Communications > NMEA 2000 Setup > Device List, select the GOS 10 Hub, then select Review > Engine Cutoff > Disable.

The Garmin OnBoard engine cutoff system is now disabled, and the engines should be restored to previous functionality.

NOTICE
The system remains disabled until you enable it again or until you turn off the system and turn it back on again. You must enable the system as soon as possible to be compliant with the AYBC A-33 standard.

To restore the Garmin OnBoard engine cutoff system functionality, select Settings menu > Communications > NMEA 2000 Setup > Device List, select the GOS 10 Hub, then Review > Engine Cutoff > Enable.

1 This option is available only during an man-overboard event initiated by an MOB tag with the captain role. This message does not appear when testing the system.
