Abstract
Hydraulic steering device for outboard motors having an end for fastening to transoms of watercrafts. The motor/propeller assembly is mounted on the end to rotate about a substantially vertical steering axis. A closed hydraulic circuit has at least one pump driven by steering unit and at least one double-acting cylinder which is slideably fitted on at least one coaxial rod. The rod sealingly projects out of a cylinder head and carries a separating piston which divides the cylinder into two variable volume chambers. At least one of the inlets/outlets of at least one of the two chambers is formed by the at least one rod. The rod has an axial hole extending from its outer end to one or more ports for communication with corresponding chambers of the cylinder. The ports are arranged to be adjacent to the piston side turned toward the cylinder head from where the rod projects.
