Abstract: An electric steering apparatus for a vessel propulsion apparatus includes a steering motor, a lock clutch, and a rotation stopper mechanism. The steering motor generates a driving force to turn the steering shaft joined to an outboard motor.

The rotation stopper mechanism is configured to switch between a lock state in which the rotation stopper mechanism restricts rotation of the casing and a release state in which the rotation stopper mechanism releases the rotation restriction of the casing.
