A hydraulic steering assembly (10) connected to the tiller arm (24) of an outboard marine engine (22) includes a piston rod (36) supported for arcuate movement about the tilt axis (B) while remaining parallel thereto. A hydraulic cylinder (42) travels along the piston rod (36). An arm (70) extends from the cylinder (42) to a first pivotal member (64) establishing a first pivotal connection about an axis (C) parallel to the tilt axis (B). A rigid link (68) extends between the first pivotal member (64) and a second pivotal member (66). The second pivotal member (66) is also connected to the tiller arm (24) and establishes a second pivotal connection about an axis (D) perpendicular to the tilt axis (B). As the cylinder (42) travels back and forth across the rod (36), the piston rod (36) oscillates about the tilt axis (B), the cylinder (42) rotates about the piston rod (36), the arm (70) rotates about the first pivotal member (64) and the link (68) rotate about the tiller arm (24) in a concerted motion providing a strong and compact linkage arrangement.
