Abstract: In a method for controlling a ship propulsion system wherein, in a first operating mode, the position of a command signal generator within a guide range including a forward and a reverse section is interpreted by a system controller as a desired power output as well as a desired travel direction, a second operating mode is provided wherein the position of the command signal generator is ignored as power output command so that the position of the command signal generator forms only as directional control device and wherein in either mode of operation, the command signal generator is automatically returned to a neutral position when the command signal generator is released by an operator.

Abstract: A method for controlling a ship propulsion system including a surface propeller, in which the desired capacity is interpreted as the target rotational value, the rotational speed control deviation is calculated from the desired rotational value and the actual rotational value of the internal combustion engine and an injection quantity for the rotational control of the internal combustion engine is determined using the rotational speed control deviation on a rotational speed controller. The trim position of the surface propeller is controlled by an arrangement controller in accordance with the capacity reserve of the internal combustion engine and the actual trim position and the effective rotational speed, the trim position being determined from the rotational speed control deviation.
