Abstract
A marine propulsion unit of a marine vessel includes a casing provided to house the 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 the 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 behind 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 behind 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 behind 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.
