Generally a Mercury engine sends data in the Smartcraft protocol. The data format and the electrical characteristics of Smartcraft are not revealed publically.
The existence of a Mercury-branded protocol convertor to provide a NMEA-2000 to Smartcraft or Smartcraft to NMEA-2000 data exchange suggests that perhaps there is some electrical incompatibility and most certainly a data format protocol incompatibility.
However, that said, there have been some developments whereby manufacturers of generic, that is non-Mercury branded, displays have been able to read data from Mercury engines.
On that basis, I think the best answer will come from Raymarine, as they will know specifically what capabilities the display device in question here will have.
This webpage from RAYMARINE seems to suggest there is newer technology related to their displays and Mercury engines, but I don't find it particularly informative about the details:
https://www.raymarine.com/multifunction-displays/accessories/engine-interfacing/mercury-vesselview/Also, exactly what engine data will be available often depends on the particular Mercury engine, and often on the capabilities provided by the protocol convertor that is sold in tiers, where more expensive models give more data.
I think--this is my guess because there are not details available to me--that perhaps what is being done now is that some non-Mercury display devices can read the Smartcraft data format directly without a protocol convertor needed to reformat the data in a NMEA-2000 parameter group equivalent, but in order to get the Smartcraft data to those devices, there must be some sort of connection to the Smartcraft network and transport of that dat to the display device. Exactly how that is done is unknown to me. Maybe the display device has a Smartcraft port. Again, check with the manufacturer of the display device that advertises it can show Mercury engine data.
