Joystick docking, counter-rotating duoprops and power trim are some of the features available on Sterndrive units from Volvo Penta. These features improve the handling, efficiency and performance of Volvo Penta, but not all Volvo Penta Sterndrives are equipped with them.
The joystick docking feature incorporates fly-by-wire software that allows for independent control of multiple engines. The feature is fully intuitive, so when the joystick is pushed to one side or the other, the boat moves sideways in the desired direction. Spinning the joystick makes the boat rotate on its own axis. Forward and backward joystick movements propel the boat in the chosen direction.
The counter-rotating duoprop design has forward-facing propellers that allow for more efficient operation in water that has not been churned up by a lower unit. Operators can adjust the pitch of the drive with the power trim to compensate for water conditions as well as optimize wake output for recreational wake boards.
