Mercury app overview
The Mercury app includes an Engine page and an Engine data page.
It is recommended that your Mercury® SmartCraft connect gateway is upgraded to the latest version of software by a Mercury® dealer.
Engine data for up to 4 engines can be displayed. The number of engines that data is displayed for is determined by the number of engines specified in the display’s boat details settings menu: .
Data for port engine(s) is displayed on the left dial, and data for starboard engine(s) is displayed on the right dial. In 3 engine systems, the right dial is also used to display data for the Center engine.
In 3 and 4 engine configurations, the RPM dial and transmission graphics are dynamic and will switch between engines under different conditions.
