Double-acting hydraulic actuating cylinder, particularly for hydraulic steering devices of outboard marine engines. The cylinder is slidably mounted on at least one rod coaxial to the cylinder sealingly protruding from at least one head of the actuating cylinder and carrying a separating piston that divides the cylinder into two variable volume chambers, each one of such two chambers has an inlet/outlet for the hydraulic fluid, each connected to one of two inlets/outlets of the pump and a sealing head for the relative sliding between the cylinder and the rod, which sealing head is integral with the cylinder itself. The rod is provided to be connected to a fastening bracket to fasten the cylinder to the engine, in a not slidable manner and in such a way as to allow the 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 at least one corresponding flat engagement surface for engaging said flattened surface.
