An outboard motor has a tiller lock which retains the rotational orientation of the outboard motor relative to a watercraft. The tiller lock allows the motor to be pivoted about a substantially horizontal tilt and trim axis while the tiller lock is engaged. The tiller lock includes a friction track advantageously arranged rearward of the tilt and trim axis. The positioning of the friction track protects the it from damage due to inadvertent contact with other components of the outboard motor mounting assembly. In particular, the friction track is protected throughout a full range of motion of the outboard motor. In addition, a pair of opposing brake members are alternately engageable with the friction track to secure the motor in a desired orientation. A bi-directional actuator handle urges either of the brake members into the friction plate independent of the other brake member to create a locking drag force which accompanies a substantially normal compressive force.
An outboard motor comprising a clamping bracket adapted to be attached to a watercraft, a pin connecting a swivel bracket to the clamping bracket, the swivel bracket being pivotal for a tilting movement relative to the clamping bracket about a substantially horizontal tilt and trim axis, the swivel bracket also enabling a steering movement of the outboard motor relative to the watercraft about a steering axis that is substantially normal to the tilt and trim axis, a tiller attached to the outboard motor to facilitate the steering movement, the tiller extending forwardly of the steering axis, a tiller locking device operable between the swivel bracket and the tiller, the tiller locking device comprising a moveable member, the moveable member being moveable between a locked position and an unlocked position, the tiller locking device arranged at least partially rearward of the pin, and an actuator coupled to the moveable member in a manner permitting selective movement of the moveable member from the unlocked position to the locked position.
An outboard motor comprising a clamping bracket adapted to be attached to a watercraft, a pin connecting a swivel bracket to the clamping bracket, the swivel bracket being pivotal for a tilting movement relative to the clamping bracket about a substantially horizontal tilt and trim axis, the swivel bracket also enabling a steering movement of the outboard motor relative to the watercraft about a steering axis that is substantially normal to the tilt and trim axis, a tiller attached to the outboard motor to facilitate the steering movement, the tiller extending forwardly of the steering axis, a tiller locking device comprising a friction track, the tiller locking device operable between the swivel bracket and the tiller, the tiller locking device arranged at least partially rearward of the pin, and the friction track is arranged entirely rearward of the tilt and trim axis.
An outboard motor mounting assembly comprising a swivel bracket pivotally attached to a clamping bracket by a pin, the swivel bracket rotatable relative to the clamping bracket about a substantially horizontal tilt and trim axis, a steering shaft journalled by the swivel bracket for movement of the steering shaft relative to the swivel bracket about a steering axis which is substantially normal to the tilt and trim axis, a tiller arm connected to the steering shaft for controlling the movement of the steering shaft, a locking mechanism operable between the swivel bracket and steering shaft so as to selectively maintain the position of the steering shaft relative to the swivel bracket, the locking mechanism arranged to lie at least partially rearward of a substantially vertical plane defined through the pin, the locking mechanism comprising a first member, the first member moveable between an engaged position and a disengaged position, and an actuator coupled to the locking mechanism in a manner permitting selective movement of the first member from the disengaged position to the engaged position.
An outboard motor comprising a powerhead connected by a driveshaft housing to a propulsion unit, the driveshaft housing connected to a steering shaft, the steering shaft journalled by a swivel bracket for rotational movement, the swivel bracket attached to a clamping bracket, the clamping bracket having a transom screw, the swivel bracket pivotal relative to the clamping bracket about a substantially horizontal tilt and trim axis, a locking mechanism operable between the swivel bracket and a tiller for securing the relative position between the swivel bracket and the tiller, the locking mechanism having a friction track interposed between at least two braking members, and the braking members being alternately engageable with the friction track.
