Talked with Yamaha tech support(Mark)today and he/they are at a loss as to why the Command Link gauge shows everything except depth. There is a possibility of a bad gauge. I'm not sure I want to go through time and expense of trouble shooting this. One way is to connect a known good transducer to the gauge and see if I get depth. If all info shows, bad transducer, if depth still fails, bad gauge. I don't know if there is an easier method. If it's a bad gauge, I have "Power Matched" system and gauges are covered under engine warranty. Bad transducer is covered under electronics warranty. Hard to see it as a bad transducer as the ducer displays everything properly on electronic display. One other possibility is NMEA connection is incorrect. Hard to see it as that, because I am getting all the other data through the Command Link gauge. This might be and issue to tackle after fishing season.
