I just got done connecting the Command Link output of my Yamaha 150 to the Sea Talk (NMEA 2000) input of my Raymarine C-80. It was surprisely easy on the electronics side. The hardest part was running the cable from the motor to the C-80. The Yamaha Command Link and RayMarine C-80 are both NMEA 2000 compliant although they use proprietary conectors between the NMEA 2000 network and the devices. When you think proprietary think $$. The Yamaha cable was $100. Having done the job, I think I could do it now for half of what I spent and make it a lot easier to do at the same time.
The net result of this is I can now see coolant temp, oil pressure, rpm, fuel flow, and alternator output/battery voltage on a custom page on the C-80. Also all engine alarms are sounded on the C-80. My choice was either doing this to get fuel flow or buying a Yamaha Command Link gauge(s) or a Lowrance LMF-400 all of which required a similar amount and expense for cables. The C-80 option was the least expensive at $300 although having done it, I think I could do it for $150.
