I have a new 998c SI still in the box waiting for my boat build completion. I will be getting a Yamaha 115 HP 4 stroke. I would like to hook up NMEA so I can see engine readings on my 998. What do I need besides a NMEA2K Adapter to do this? The HB website says something about a NNEA2000 backbone. Does the engine have this or do I need other parts and where might I find these?
Thanks for any help.
