Gents I am working on my new to me boat and am trying to figure out why engine data is not displayed on my lowrance HDS gen 3. When I bought it the boat only had 30 hours on it and I don’t believe the owner even knew about this feature. I verified the nmea backbone appears to be installed correctly. From left to right in photo engine line to mercury then power then line to the sonar then the line to my spot lock trolling motor that does work correctly with the lowrance. I also took a photo of the gateway in the outboard that has a green light displayed for nmea and gain. Any ideas why no data on the lowrance? Could it be a setting/user error? Thank you in advance for any advice on where to start. Engine is a 2016 mercury pro Xs 150hp

I called European Marine(Rhonda or Don) and they told me what and how to connect. 1 864 421 0444 Good people.
