ABSTRACT:
A tiller arm and steering bracket assembly where the tiller arm is pivotally coupled to the steering bracket such that it can be selectively positioned in either a generally horizontal position or a generally vertical position. The tiller arm includes an underside having interference ribs that contact the steering bracket when the tiller arm is placed in the horizontal position. The interference ribs each have a retaining ledge that supports the tiller arm on the head portion of the steering bracket in an upright position substantially perpendicular to the steering bracket when it is placed in the vertical position. The steering bracket has integral crest formations which contact the retaining ledges to provide additional support to the tiller arm when it is placed in the vertical position. A bore formed through the steering bracket accepts a retaining pin that contacts the tiller arm at a point which prevents the tiller arm from unintentionally returning to the horizontal position. Additionally, the steering bracket may have a recess and a channel formed through the steering bracket for accepting and mounting thereto a starter switch and starter mechanism.
