Hi Jeff, pictured below is my helm. My gauges are like me...the non smart version. There is a screen on the chartplotter to show engine data, but non of it registers, it doesn't appear to be connected to the outboard.
I may be wrong and it just needs to be configured correctly, but my guess is I don't have the NMEA 2000 network connected between the plotter and the outboard.
If that proves to be the case (and I'm sure it is) I am assuming to connect the 2, I would need a NMEA 2000 wiring and t's (a starter kit?), plus an interface of some kind to connect the merc fourstroke to the wiring.
