Mercruiser to E80 Classic wiring?

Welcome to the Raymarine Forum Rick,

Raymarine MFDs adhere the NMEA 2000 instance numbering convention for more than one instance of type of device when such devices are installed across the width of the hull. Within this convention, instance number 0 will be assigned to the device which is fully to port. Then instance numbers will then incrementally increase from port to starboard. Accordingly, the instance numbers which should be assigned to a boat with three engines would be as follows:
- port engine: 0
- center engine: 1
- starboard engine: 2
