There is provided an intake apparatus of an engine for an outboard motor. An intake manifold, a throttle body and an intake silencer box are arranged at one of right and left sides of an engine block which is configured such that an axial direction of a cylinder coincides with a front and rear direction of the outboard motor. An intake duct communicating with an intake introduction port provided at an upper part of an engine cover is coupled to an upstream end of the intake silencer box. A first water separation part is arranged between the intake introduction port and the intake duct. A second water separation part is provided below a duct part of the intake duct. The second water separation part is formed by providing a drain hole at a bottom part of a resonator chamber part communicating with the duct part to reduce an intake noise.

Intake apparatus of engine for outboard motor

An operating device of an electric outboard motor has a steering bar-shaped handle projecting forward and pivotally supported on a hull to be able to steer right and left. A propeller of the electric outboard motor is driven by an electric motor driven by power supplied from a power supply. On a tip portion of the steering bar-shaped handle, the operating device is provided with an accelerator grip that is made to pivot on an axial center normally and reversely from a neutral position to adjust an amount of power to be supplied to the electric motor according to a pivot amount. The operating device includes in the accelerator grip or in vicinity of the accelerator grip, an accelerator grip fixing mechanism that fixes a pivot position of the accelerator grip at the neutral position to be able to release a fixation easily.

Operating device of electric outboard motor

There is provided an intake apparatus of an engine for an outboard motor. An intake manifold, a throttle body and an intake silencer box are arranged at one side of an engine block configured such that an axial direction of a cylinder coincides with a front and rear direction of the outboard motor. The intake silencer box includes a main body part having a first air passage configured to guide air in the axial direction of the cylinder and coupled to the upstream end of the throttle body, and a cover part having a second air passage coupled to the first air passage and opened to an outside. An air filter element arranged orthogonal to an air flowing direction and interposed between the first air passage and the second air passage is fixed to a mating surface of the main body part and cover part.

Provided is an electric outboard motor that includes a drive motor, which is an AC motor, as a drive source. The electric outboard motor includes: an outboard motor main body that includes the drive motor and an inverter that converters a direct current to an alternating current to supply the alternating current to the drive motor; a control/power supply unit that is formed separately from the outboard motor main body and that can supply the direct current to the inverter; and a connection cable that electrically connects the outboard motor main body and the control/power supply unit. The inverter and the drive motor are stacked and arranged in an axial direction of a rotation output axis of the drive motor. Part of the inverter falls within an outline of the drive motor in a view in the axial direction of the rotation output axis of the drive motor.
