Abstract
An outboard motor includes a bracket, an outboard motor main body including an upper portion attachable to a hull via the bracket and a lower portion located below the upper portion and on which a propeller is provided, a first steering mechanism to rotate the upper portion in a right-left direction with respect to the hull, and a second steering mechanism to rotate the lower portion in the right-left direction with respect to the upper portion.

An outboard motor comprising:
- a bracket;
- an outboard motor main body including an upper portion attachable to a hull via the bracket and a lower portion located below the upper portion and on which a propeller is provided;
- a first steering mechanism to rotate the upper portion in a right-left direction with respect to the hull;
- and
- a second steering mechanism to rotate the lower portion in the right-left direction with respect to the upper portion;
- wherein
- the lower portion has an angular range in which the lower portion is rotatable in the right-left direction with respect to the upper portion by the second steering mechanism;
- the upper portion has an angular range in which the upper portion is rotatable in the right-left direction with respect to the hull by the first steering mechanism;
- and
- the angular range of the lower portion is larger than the angular range of the upper portion.

A marine vessel comprising:
- a hull;
- and
- an outboard motor attached to the hull;
- wherein
- the outboard motor includes:
- a bracket;
- an outboard motor main body including an upper portion attached to the hull via the bracket and a lower portion located below the upper portion and on which a propeller is provided;
- a first steering mechanism to rotate the upper portion in a right-left direction with respect to the hull;
- and
- a second steering mechanism to rotate the lower portion in the right-left direction with respect to the upper portion;
- wherein
- the lower portion has an angular range in which the lower portion is rotatable in the right-left direction with respect to the upper portion by the second steering mechanism;
- the upper portion has an angular range in which the upper portion is rotatable in the right-left direction with respect to the hull by the first steering mechanism;
- and
- the angular range of the lower portion is larger than the angular range of the upper portion.

A marine vessel comprising:
- a hull;
- and
- an outboard motor attached to the hull;
- wherein
- the outboard motor includes:
- a bracket;
- an outboard motor main body including an upper portion attached to the hull via the bracket and a lower portion located below the upper portion and on which a propeller is provided;
- a first steering mechanism to rotate the upper portion in a right-left direction with respect to the hull;
- and
- a second steering mechanism to rotate the lower portion in the right-left direction with respect to the upper portion;
- wherein
- both the first steering mechanism and the second steering mechanism are driven when a steering angle of the outboard motor is larger than a predetermined steering angle or when a steering speed of the outboard motor is higher than a predetermined speed;
- and
- only the second steering mechanism is driven when the steering angle is equal to or smaller than the predetermined steering angle or when the steering speed is equal to or lower than the predetermined speed.
