One of the most basic functions of a dashboard screen is the gauge cluster. It provides the driver with information on engine water temperature, battery voltage, fuel level, oil pressure and rpms. Most dashboard screens have some sort of speed or cruise control, whether it be PerfectPass, Zero Off or a system developed by the wakeboarding boat manufacturer. Ballast level control is also a standard feature on dashboard screens, as well as stereo controls. Aside from those standards, each boat really differentiates itself from other manufacturers by having multiple options controlled by the screen.
