ABSTRACT:
An outboard motor has a steering lock which retains the rotational orientation of the outboard motor relative to a watercraft. The steering lock allows the motor to be pivoted about a substantially horizontal tilt and trim axis while the steering lock is engaged. The steering lock includes a friction plate which is advantageously straight. The friction plate is connected to the steering arm, and movement of either the steering arm or the friction plate requires movement of the other. At least one friction lock engages with the friction plate to secure the motor in a desired orientation. The friction lock is rigidly affixed to the outboard motor. The friction lock includes one or more disc pads. Movement of an operation lever urges the disc pads against the friction plate hold the friction plate and consequently, the steering arm, in a predetermined position.
