There is provided a hydraulic steering assembly for applying a force to two or more marine propulsion units. Each propulsion unit has a steering axis and a tilt axis. The tilt axis is generally perpendicular to the steering axis thereof. Each propulsion unit is rotatabl e about the steering axis and is supported for arcuate movement about the tilt axis thereof. The steering assembly comprises a hydraulic steering actuator including a cylinder and an elongated piston rod. The cylinder has a first end and a second end. The elongated piston rod is reciprocatingly mounted within the cylinder and extends through the cylinder for movement along a piston rod axis. A pair of support arms are pivotable about the tilt axis of a first propulsion unit. The support arms a re connected to the piston rod axis allowing arcuate movement of the piston rod about the tilt axis, while maintaining the piston rod axis parallel to the tilt axis. A pivot member is pivotally mounted on t he first said propulsion unit for pivoting about a first link axis, which is parallel to the steering axis . The actuator is pivotally connected to the pivot member for pivoting about a second link axis, which i s parallel to the piston rod axis. A connecting member is connected to the actuator. The connecting member includes a portion forconnecting the connecting member to the actuator and a portion fo r pivotally connecting an elongated member to the connecting member.
