An apparatus for driving and controlling a watercraft or the like having at least one pair of steerable propellers, the steerable propellers of each pair being located substantially symmetrically on opposite sides of the center line of the watercraft, such center line extending through the center of lateral resistance of the watercraft. A control element is provided for carrying out control movements in two degrees of freedom. Each control movement acts for remote control of the steerable propellers through transmitters corresponding respectively to such steerable propellers. Movement of the control element in one degree of freedom effects a rotation about an axis for controlling, through the transmitters, a synchronous pivoting of the servo propellers of each pair. Movement of the control element in the second degree of freedom effects movement of a rack element for controlling, through the same transmitters, an oppositely directed pivoting of the servo propellers relative to one another.
