in a method for calibrating a system for controlling thrust and steering of a drive arrangement in a watercraft , the system includes an operating device adapted for indicating a requested direction of travel of the watercraft , the operating device being connected to a control unit for providing corresponding thrust and steering commands to the drive arrangement . the method includes receiving an activation command in the control unit , for beginning the calibration , detecting any movements of the operating device , storing values corresponding to the movements in the control unit together with corresponding thrust and steering values , and repeating the detecting step and the storing step until a termination command is received in the control unit , thereby using the stored values in subsequent operation of the operating device for indicating the direction of travel of the watercraft . an arrangement for calibrating a system for controlling thrust and steering of a drive arrangement in a watercraft is also provided .
