Abstract

A transportable outboard motor has a tiller which is pivotable about a lateral tilt axis into a plurality of tilt positions and also pivotable about an axial yaw axis into a plurality of yaw positions. The tiller is pivotable about the axial yaw axis into a straight-ahead position, into a port yaw position which is oriented towards the port side relative to the straight-ahead position, and into a starboard yaw position which is oriented towards the starboard side relative to the straight-ahead position. The tiller is pivotable downwardly about the lateral tilt axis from the port yaw position, and downwardly about the lateral tilt axis from the starboard yaw position. Pivoting the tiller into the plurality of yaw positions creates space for a user to manually grasp a swivel tube and thereby lift the transportable outboard motor from a rear-laydown position.

First claim

What is claimed is:

1 . A transportable outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front to a rear in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the transportable outboard motor comprising a tiller which is pivotable about a lateral tilt axis into a plurality of tilt positions relative to the transportable outboard motor and also pivotable about an axial yaw axis into a plurality of yaw positions relative to the transportable outboard motor, wherein the tiller is pivotable about the lateral tilt axis out of each of the plurality of yaw positions into a respective downward tilt position in which the tiller is angled downwardly relative to a plane extending in the longitudinal direction and the lateral direction.

2 . The transportable outboard motor according to claim 1 , wherein the tiller is pivotable about the axial yaw axis into a straight-ahead position, into a port yaw position which is oriented towards the port side relative to the straight-ahead position, and into a starboard yaw position which is oriented towards the starboard side relative to the straight-ahead position, and wherein the tiller is pivotable downwardly about the lateral tilt axis from the port yaw position, and further wherein the tiller is pivotable downwardly about the lateral tilt axis from the starboard yaw position.

3 . The transportable outboard motor according to claim 2 , further comprising a steering arm extending forwardly from a midsection of the transportable outboard motor, wherein the tiller is coupled to the steering arm.

4 . The transportable outboard motor according to claim 3 , further comprising a swivel tube coupled to the steering arm, the swivel tube configured to seat in a transom bracket assembly configured to support the transportable outboard motor relative to a marine vessel.

5 . The transportable outboard motor according to claim 4 , further comprising a cowling and an anti-ventilation plate which together with a rear of the cowling supports a remainder of the transportable outboard motor above a ground surface in a rear laydown position, wherein the transportable outboard motor may be lifted out of the rear laydown position via either or both of the swivel tube and the tiller in the respective downward tilt position, wherein pivoting the tiller out of one of the port yaw position or the starboard yaw position into the respective downward tilt position creates space for a user to manually grasp the swivel tube and thereby lift the transportable outboard motor from the rear laydown position.

6 . The transportable outboard motor according to claim 4 , further comprising a cowling and an anti-ventilation plate which together with a rear of the cowling supports a remainder of the transportable outboard motor above a ground surface in a rear laydown position, wherein the transportable outboard motor may be lifted out of the rear laydown position via either or both of the swivel tube and the tiller in the respective downward tilt position, wherein pivoting the tiller downwardly about the lateral tilt axis from one of the port yaw position or the starboard yaw position stores the tiller alongside and adjacent the swivel tube for transport of the transportable outboard motor via the swivel tube.

7 . A transportable outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front to a rear in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the transportable outboard motor comprising a tiller which is pivotable about a lateral tilt axis into a plurality of tilt positions relative to the transportable outboard motor and also pivotable about an axial yaw axis into a plurality of yaw positions relative to the transportable outboard motor, wherein the tiller comprises a tiller arm and a base bracket assembly, the base bracket assembly comprising a yaw bracket which is fixedly coupled to the transportable outboard motor and a steering bracket which pivotably couples the tiller arm to the yaw bracket for movement about the axial yaw axis.

8 . The transportable outboard motor according to claim 7 , wherein the tiller arm is pivotable through at least 90 degrees relative to the axial yaw axis, and further wherein the plurality of yaw positions spans at least 90 degrees relative to the axial yaw axis.

9 . The transportable outboard motor according to claim 7 , wherein the tiller arm is pivotable through at least 180 degrees relative to the axial yaw axis, and further wherein the plurality of yaw positions spans at least 180 degrees relative to the axial yaw axis.

10 . The transportable outboard motor according to claim 1 , further comprising a yaw lock configured to lock the tiller in the plurality of yaw positions relative to the axial yaw axis, wherein unlocking the yaw lock facilitates movement of the tiller into a new yaw position of the plurality of yaw positions.

11 . A transportable outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front to a rear in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the transportable outboard motor comprising a tiller which is pivotable about a lateral tilt axis into a plurality of tilt positions relative to the transportable outboard motor and also pivotable about an axial yaw axis into a plurality of yaw positions relative to the transportable outboard motor, wherein the plurality of tilt positions comprises a downward tilt position in which the tiller is angled downwardly in the axial direction so as to facilitate carrying of the transportable outboard motor via the tiller, and wherein outboard motor has a center of gravity which is centered below the tiller in the downward tilt position thus facilitating carrying of the outboard motor via the tiller.

12 . The transportable outboard motor according to claim 1 , wherein the respective downward tilt position is at least 45 degrees downwardly relative to a horizontal plane defined by the lateral direction and the longitudinal direction.

13 . The transportable outboard motor according to claim 1 , wherein the respective downward tilt position is at least 75 degrees downwardly relative to a horizontal plane defined by the lateral direction and the longitudinal direction.

14 . The transportable outboard motor according to claim 1 , further comprising a tilt mechanism which is movable into an engaged position the tiller is retained in a selected one of the plurality of tilt positions, and into a disengaged position in which the tiller is freely pivotable about the lateral tilt axis.

15 . The transportable outboard motor according to claim 14 , wherein the tilt mechanism facilitates pivoting of the tiller about the lateral tilt axis from each of the plurality of yaw positions.

16 . A transportable outboard motor extending from a top to a bottom in an axial direction, from a port side to a starboard side in a lateral direction which is perpendicular to the axial direction, and from a front to a rear in a longitudinal direction which is perpendicular to the axial direction and perpendicular to the lateral direction, the trans
