Abstract
A marine propulsion unit of a marine vessel includes a casing provided above a duct to house a steering shaft and a controller configured or programmed to control driving of a propeller, the casing being rotatable by the steering shaft, a power supply wire to supply power to a stator, and a signal wire to transmit a drive signal to the controller. The power supply wire and the signal wire are located outside and along the casing so as to pass in front of the steering shaft along a rotation direction of the steering shaft from a first side to a second side of the casing, the first and second sides being opposite to each other with respect to a forward-rearward direction in a plan view thereof.

A marine propulsion unit of a marine vessel, comprising:
- a duct including a stator;
- a propeller including
- a rim including a rotor, the rotor facing the stator, and
- a blade provided radially inwardly of the rim;
- a steering shaft that extends in an upward-downward direction of the marine vessel, and is rotatably connected to the duct;
- a casing provided above the duct to house the steering shaft and a controller configured or programmed to control driving of the propeller, the casing being rotatable by the steering shaft;
- a power supply wire to supply power to the stator;
- and
- a signal wire to transmit a drive signal to the controller, wherein
- the power supply wire and the signal wire are located outside and along the casing so as to pass in front of the steering shaft along a rotation direction of the steering shaft from a first side of the casing to a second side of the casing, the first and second sides being opposite to each other with respect to a forward-rearward direction of the marine vessel in a plan view thereof.
A marine vessel comprising:
- a hull;
- and
- a marine propulsion unit on the hull, the marine propulsion unit including:
- a duct including a stator;
- a propeller including
- a rim including a rotor, the rotor facing the stator, and
- a blade provided radially inwardly of the rim;
- a steering shaft that extends in an upward-downward direction of the marine vessel, and is rotatably connected to the duct;
- a casing provided above the duct to house the steering shaft and a controller configured or programmed to control driving of the propeller, the casing being rotatable by the steering shaft;
- a power supply wire to supply power to the stator;
- and
- a signal wire to transmit a drive signal to the controller, wherein
- the power supply wire and the signal wire are located outside and along the casing so as to pass in front of the steering shaft along a rotation direction of the steering shaft from a first side of the casing to a second side of the casing, the first and second sides being opposite to each other with respect to a forward-rearward direction of the marine vessel in a plan view thereof.
