Abstract
An outboard motor includes an upper unit including a drive motor and a first transmission mechanism, a lower unit including a propeller and a propeller shaft, a drive shaft extending from the upper unit to the lower unit, a connecting mechanism that connects the lower unit to the upper unit so that the lower unit is pivotable, a steering motor serving as a power source for pivoting the lower unit relative to the upper unit, and a third transmission mechanism that transmits rotation of the steering motor to the lower unit. The drive shaft is disposed in front of an output shaft of the drive motor and the steering motor is disposed below the drive motor and behind the drive shaft.
Claims7
An outboard motor comprising:
- an upper unit including:
- a drive motor serving as a power source configured to rotate a propeller;
- and a first transmission mechanism configured to transmit rotation of the drive motor to a drive shaft;
- a lower unit including:
- a propeller shaft in which the propeller is provided;
- and a second transmission mechanism configured to transmit rotation of the drive shaft to the propeller shaft;
- the drive shaft extending in a vertical direction from the upper unit to the lower unit;
- a connecting mechanism configured to connect the lower unit to the upper unit so that the lower unit is pivotable about an axis of the drive shaft;
- a steering motor provided in the upper unit and serving as a power source configured to pivot the lower unit relative to the upper unit;
- and
- a third transmission mechanism provided between the upper unit and the lower unit and configured to pivot the lower unit relative to the upper unit by transmitting rotation of the steering motor to the lower unit, wherein
- the drive shaft is disposed in front of an output shaft of the drive motor and the steering motor is disposed below the drive motor and behind the drive shaft.
