I am having one helluva time getting this done. Here is the situation. I have an 06 280ss, with twin 6.2 horizon bravo 3's. according to Mercruiser tech, they are Smartcraft capable and can be converted to display Nmea 2k engine data. It was working on a basic analog only system. I have had a professional installer, install a Garmin 741, Mercmonitor and a garmin transducer with the mission of getting digital engine data on the Garmin. In my first discussion with Merc about this they said no problem, install a gateway and plug it into your nmea2k network and data will show up, but the engines needed to be reprogrammed for starboard and port as both of them shipped as starboard engines. Call number 2 to merc, you will also need a merc monitor gauge because this gauge converts the data to nmea 2k. Call number 3, after the installation has been completed....the engines need to be reprogrammed to make this work and by the way none of your analog gauges will work once this is done. Has anyone in this forum, successfully added a merc monitor and do your analog gauges still work? Did any other unforeseen problems get created, like are my throttles going to stop working now?
