Abstract: A tiller arm for outboard motors includes a first portion adapted to be coupled to the outboard motor and a second portion adapted to be coupled to a command terminal. The first and the second portions of the tiller arm are telescopically engageable to one another, and a blocking system between the first and second portions is configured to block a mutual sliding at predetermined positions.

Abstract: Steering control system for a watercraft with a steering tiller manually operated and operatively connected to a direction changing member acting on or into the water, such as a rudder plate or an outboard motor; a device locking the steering tiller in the steering position. which can be activated for maintaining the tiller in a predetermined angular position and can be deactivated for allowing the tiller to be moved in a different angular position to carry out a change in the direction. The locking device is of the hydraulic type, that is, oil-hydraulic type, and includes a hydraulic cylinder having a rod that is fastened stationary to the transom of the watercraft and a cylindrical body that is movable along the rod and is connected to a steering arm of the motor or of the rudder member, or vice versa, there being provided a closed circuit for flowing the oil between the two chambers of the cylinder, within which circuit there is provided a valve opening and closing the circuit, which locking device can be activated/deactivated by an actuator that opens/closes the valve opening and closing the circuit. The system further includes an interposition element between the steering tiller and the watercraft direction changing member, the tiller being pivotably articulated to such element, and a member transforming the pivoting movement of the tiller with respect to the interposition element into commands actuating the valve.

Abstract: A steering control system for a watercraft includes a device locking a steering tiller, which can be activated or deactivated for maintaining the tiller in, or moving it from, a predetermined angular position. The locking device includes a hydraulic cylinder having a rod fastened to the transom of the watercraft and a cylindrical body movable along the rod and connected to a steering arm of the motor or of the rudder member. A closed circuit, opened or closed by a valve, flows oil between the two chambers of the hydraulic cylinder and the locking device can be activated or deactivated by an actuator that opens or closes the valve. An interposition element between the steering tiller and a watercraft direction changing member is pivotably articulated to the tiller, and a member transforms the pivoting movement of the tiller relative to the interposition element into commands actuating the valve.
