A double-effect hydraulic actuating cylinder, particularly for hydraulic steering devices of outboard marine engines, is slidably mounted on a rod coaxial with the cylinder and sealingly protruding from a head of the actuating cylinder, carrying a separating piston that divides the cylinder into two variable volume chambers. Each chamber has an inlet/outlet for the hydraulic fluid that are respectively connected to one of the inlets/outlets of a pump, and a sealing head is disposed between the cylinder and the rod and is integral with the cylinder. The rod is adapted to be connected to a fastening bracket to non-slidably fasten the cylinder to the engine, allowing a relative rotation of the engine with respect to the transom along an axis parallel to the axis of the rod. The rod has at least one flattened surface to be grasped by a tool having a correspondingly flattened engagement surface.
