Abstract
A marine vessel electric propulsion system includes an electric motor, a propulsive force generator to be driven by the electric motor to generate a propulsive force, an operator to be operated by a user to adjust the power output of the electric motor, and a controller. The controller is configured or programmed to control the power output of the electric motor based on an operation of the operator, and to change a power output gain characteristic of the electric motor with respect to an operation amount of the operator in response to a gain change command.
