The Garmin OnBoard™ engine cutoff system consists of a central hub that connects to power and to the same NMEA 2000^® network as a Garmin^® chartplotter or other compatible display device. The hub monitors the presence of Man Overboard (MOB) tags wirelessly and can react in different ways when a tag moves outside the range of the hub. For example, if a passenger falls out of the vessel while underway. The system can provide an alert only, or it can also cut off the engine, depending on how you program it based on the roles of the tags.

When planning the installation, observe these considerations.

• You should install the GOS™ 10 hub near the helm so it can monitor the presence of the boat captain most effectively.

• The hub requires power, so you must install it in a location where you can route power and ground wires to a 12 VDC power source.

• You should make sure that you can reach the existing NMEA 2000 backbone to connect the hub. If you do not currently have a NMEA 2000 network on your boat, you must install one before you can use the Garmin OnBoard system.

• To enable the Garmin OnBoard system to turn off the boat engines, you must connect the hub to the appropriate engine wiring. Depending on your boat, you can connect the hub to either an existing kill switch or to the ignition signal wire to the engines. This connection should be made near the helm.
