(54)	Hydraulic steering system for marine motors

(57) A hydraulic steering system (1) for marine motors comprises a supporting rod (3) designed to be disposed at the stem of the boat in a transverse direction with respect to the longitudinal direction of the boat and designed to be supported by a flange (60) in which a marine motor (61) is pivoted, a hydraulic cylinder (5) mounted slidably on a fixed shaft (4) disposed parallel to the supporting rod (3) and defining two chambers (57, 58) supplied with oil to allow translation of the cylinder on the fixed shaft, and an articulated system (7) which connects the hydraulic cylinder (5) to a front bar (64) of the motor (61); ducts (42, 43 44, 45) which supply oil respectively to the two chambers (57, 58) of the hydraulic cylinder (5) being formed inside the shaft (4).
