Thats normal. Ive always assumed that the way the gauge starts up to load data. By the way, that is not Mercury Smart Craft. That is Bass Cat NexSys gauges you have which is upgraded package over the standard Beede gauges.
That is the SmartCraft information system which is why it loads to the SmartCraft screen. That information is scrolling and if you dont control the display after is starts then the touch pad has an issue. BCB
