The tilt control switch is attached to the handle case near the throttle grip so as to be located further inside.

In the steering handle of the above outboard motor, the handle case is divided into an upper cover and a lower cover, and the shift transmission link mechanism is attached to the upper cover side behind the tilt control switch. It is preferable that both cover joint portions of the handle case are formed as flange portions at least above the operation button of the switch.

Further, it is preferable to form a guard portion protruding laterally below the operation button of the tilt control switch.

[0009]

[Operation] With the above configuration, the switch for tilt control can be operated with one hand while holding the throttle grip during back troll, and the handle case is located above the operation button of the switch rather than the operation button. Since it projects to the side, it is possible to prevent accidental operation of the power tilt device during another operation without accidentally touching the operation button for tilt control from above during a throttle operation or the like.

By attaching the link mechanism of the shift transmission section to the upper cover side behind the tilt control switch, it is possible to secure a space on the lower surface of the handle case near the throttle grip. The switch can be installed as close as possible to the throttle grip without protruding too much downward.

Further, by forming the joint portion of the upper and lower covers of the handle case as a flange portion, a portion which largely protrudes to the side of the handle case above the operation button can be formed. The inadvertent contact can be prevented more reliably. Further, by forming the guard portion below the operation button, inadvertent contact with the operation button below is similarly prevented.
