Axius is based on the same software originally developed by Cummins MerCruiser Diesel (CMD) for the Zeus pod drive system. As with Zeus, a single intuitive joystick allows a captain to move an Axius-equipped boat along three separate axes: left to right, forward or back, or fully sideways. Push, pull, or twist the joystick knob and the boat responds in kind. Exaggerating those same movements will bump up rpm (limited to just under 2000), enabling the driver a little more speed. Turn and face backward to ease into a slip, and the controls retain their same intuitive operation.
