Functions: Functions depend on what engine it is connected too. For all engines 150HP and above: RPMS, engine trim readings, oil pressure, water temperature, battery volts, engine codes, low oil pressure and high water temp warnings,engine maintenance reminder, variable trolling speed control(if engine is capable), water pressure(with optional sensor installed). Engines below 150hp, all of the same functions as above minus oil pressure readings. These engines only have a oil pressure switch, not a oil pressure sending unit.
