Abstract: A watercraft steering device can include at least one of steerage status detection device configured to detect a steerage status following an operation of the steering wheel, running status detecting device configured to detect a running status of the watercraft, watercraft propulsion unit status recognition device configured to recognize a status of an outboard motor such as an installation number thereof, and electric motor status detection device configured to detect a status of an electric motor, and can further include a lower unit turning force characteristic computation device configured to compute a lower unit turning force characteristic based on a detection value from at least one of the device, and an ECU configured to control at least one of a reaction force to the steering wheel, a limit lower unit turning angle, and a propulsive force based on a computed lower unit turning force characteristic and/or selecting the electric actuator to operate.

Abstract: The invention relates to a steering device for a vessel comprising at least one rudder arranged to pivot about a substantially vertically extending rudder pivoting axis and comprising at least one operating handle mounted on an operating handle pivot shaft extending in the longitudinal direction of the vessel, which operating handle is arranged to pivot in an imaginary plane extending substantially vertically and transversely to the longitudinal axis of the vessel, the operating handle being connected to the or each rudder via at least one coupling mechanism, so that a pivoting movement of the at least one operating handle causes a pivoting movement of the or each rudder about the rudder pivoting axis, wherein the or each coupling mechanism is formed by a set of cooperating gear segments, of which a first one is mounted on the or each rudder or a rudder pivot shaft connected thereto, and the second one is mounted on the at least one operating handle pivot shaft.

Abstract: An adapter for accommodating variations in size and design of outboard motor powerheads, to couple a power steering servo unit thereto, utilizing existent mounting brackets and steering brackets without restriction on powerhead use, characterized by an anchor socket pivoted on a transverse mounting bracket axis to secure a motor operated tiller member at a fixed steering position that shifts its steering center eccentrically with respect to the turning center of the powerhead, the anchor socket accommodating angular displacement caused by said eccentricity.

Abstract: A remote steering control for outboard powerheads on boats, having a reversible motor and pinion mounted on a bracket moving with the powerhead engaging a tiller segment on the motor mount, steering right and left in response to a remote and portable hand held control.

Abstract: A boat steering mechanism for permitting a remotely mounted rudder control by means of a push-pull control cable, comprising a rack being formed with a groove for inserting an inner cable, a projection projecting from the center or its vicinity of a rack casing into which the rack is slidably inserted, an inclined hole for slidably inserting the inner cable, perforated through the projection into the groove, a triangular guide portion having an inclined plane which continues from the lower end of the inclined hole and projecting from the inner wall of the rack casing into the groove so as to be inserted into the groove and a fitting member for fastening on one end of the inner cable, secured to the rack at one end of the groove, whereby the push-pull control cable can be provided with a large curvature and the sliding resistance of the whole mechanism can be decreased.
