Abstract
In an outboard motor, a controller controls an electric motor. An output outputs a predetermined notification information in response to a notification command signal output from the controller. When the controller receives a shut-off signal indicating that a semiconductor fuse is off, the controller outputs the notification command signal and causes the output to output notification information. When the controller receives a recovery operation signal indicating a predetermined operation performed by a user from an operator in a state where the semiconductor fuse has turned off, the controller outputs a recovery command signal to the semiconductor fuse.
Claims10
An outboard motor comprising:
- an outboard motor body including an engine;
- an electric motor that moves the outboard motor body;
- an electrical circuit that electronically connects the electric motor to an electric power supply;
- a semiconductor fuse located in the electrical circuit and that switches from an on state that allows electric power to be supplied from the electric power supply to the electric motor to an off state that shuts off the electric power supplied from the electric power supply to the electric motor when a predetermined fail condition is satisfied, and that turns back to the on state from the off state upon receipt of a predetermined recovery command signal;
- an operator that outputs a signal indicating an operation by a user;
- a controller configured or programmed to control the electric motor;
- and
- an output that outputs predetermined notification information in response to a notification command signal output from the controller;
- wherein
- the controller is configured or programmed to:
- output the notification command information and cause the output to output the notification information when the controller receives a shut-off signal indicating that the semiconductor fuse is in the off state;
- and
- output the recovery command signal to the semiconductor fuse when the controller receives a recovery operation signal indicating a predetermined operation by the user in a state in which the semiconductor fuse is in the off state;
- the operator includes a switch;
- and
- the operator outputs the recovery operation signal when the switch is operated.
