Exp: If the J1939/NEMA reads that the motor is overheating, does an alarm sound for the ECM (which protects the motor) or the NEMA display. Far out example, but hope the drift is caught

Looks like you need a converter/gateway for older motors. I have MEFI3 motors myself and would love to do an in-dash plotter with engine monitoring.
Looks like this is the ticket.

Also found these that are more of a true "analog to digital" converter. Basically wire right to analog gauge senders and you can program the unit for each particular channel.

Thanks for all that info. I have something to go on and reading about these components I have a good idea where I need to go with my idea.
It looks like the converters are the real time data stream and the best for me. The updating type means processing and I don't want that in the way. Converting right off the sender to NMEA 2000 looks like the way I would go since it is more like live analog.
I still want to talk to Merc to understand more about their communication protocol. Finding that out could also help me to customize the conversions.
You guys have been an immense help. Thank you all big time !!!!

I have 05 500efi engines and I am in the same situation. I called Merc with the engine serial numbers and was told no smartcraft capability. I was looking into the Noland units as I am planning on keeping most gauges and running a Simrad Go7. I will watch to see what you decide on.
