Abstract
A watercraft propulsion system includes an electric propulsion device attachable to a hull, an indicator located above a draft line of the hull and operable to indicate to surroundings of the electric propulsion device information about the state of the electric propulsion device, and a controller. The controller has a plurality of control modes including an electric propulsion device enabled mode in which the electric propulsion device is enabled to be driven, and is configured or programmed to perform an indicator control operation in the electric propulsion device enabled mode to actuate the indicator to indicate that the electric propulsion device is in a drivable state.

A watercraft propulsion system comprising:
- an electric propulsion device attachable to a hull and including a propeller to be located at an underwater position below a draft line of the hull;
- a lift to move up and down the propeller of the electric propulsion device between the underwater position and an above-water position above the draft line of the hull;
- an indicator provided on the hull and directly attached to the hull such that the indicator is located above the draft line of the hull even when the propeller is located at the underwater position and operable to indicate to surroundings of the electric propulsion device information about a state of the electric propulsion device;
- and
- a controller including a plurality of control modes including an electric propulsion device enabled mode in which the electric propulsion device is enabled to be driven, and configured or programmed to perform an indicator control operation in the electric propulsion device enabled mode to actuate the indicator to indicate that the electric propulsion device is in a drivable state.
