Can I bypass using the xFOB to run the engine? (In case of loss or failure)

Yes, on the MOB+ you can override the system in two ways;

1. The xHUB installed in the boat has a button. If you press & hold this button for 10 seconds it will enter Override Mode. In Override Mode you can drive the boat without the need to connect the xFOB. The xHUB will sound a bip every 30 second and blink yellow every 2 seconds to remind you that you are not wirelessly connected. The Override Mode will shut down after 8 hours. After 8 hours you need to press & hold for 10 more seconds to re-enter Override Mode.
2. In the unlikely event that there is a failure to the xHUB you can physically override the unit. The cable leading to the xHUB comes with an emergency plug, this plug can be inserted into the IP68 connector on the cable wires (kill switch wires) leading to the engine(s). This will physically jump the the kill switch wires to bypass the kill switch allowing the engines to start and run.
