摘要： An outboard motor is equipped with a centrifugal clutch located between the crankshaft of an engine and a rotor of an electric motor for, when the engine operates, transmitting its output to through the rotor to a propeller, and with a motor output transmission mechanism for, when the engine does not operate, transmitting the output of the motor to the crankshaft. The engine can therefore be started by the motor used to drive the propeller. As a result, there is no need to install a separate electric motor for engine starting, so that starting of the engine by electric power can be made possible with minimum increase in the size and cost of the outboard motor.

摘要： A duct member is disposed around outer peripheries of an engine and an engine-driven generator to define a continuous cooling-air passage between the duct member and the outer peripheries. A cooling fan is disposed in the cooling-air passage to generate a flow of cooling air from one end of the cooling-air passage to the other end during operation of the engine. An intake box is connected to one end of the cooling-air passage and has an air-intake port. A muffler box is connected to the other end of the cooling-air passage, has an air-discharge port, and accommodates an exhaust muffler of the engine. A sound-insulating housing is connected between the intake box and the muffler box to surround the duct member in order to insulate sound emitted from the duct member.
