摘要： A marine propulsion system (102, 202, 302) includes an outboard motor (102a, 302a) including an outboard motor engine (1), a propulsion generator (2) configured to be driven by the outboard motor engine, and an electric starter (4) configured to start the outboard motor engine, the outboard motor installed on a hull (101), and an outboard motor capacitor (7) provided in the outboard motor and configured to supply, to the starter, power to start the outboard motor engine, the outboard motor capacitor having a higher output per unit volume than a lead storage battery (B1, B201).

摘要： An outboard motor (101) includes an engine (1), a generator (5) configured to generate power by driving of the engine, a driving force transmitter (2) configured to transmit a driving force from the engine, a propeller shaft (3) configured to rotate by switching from a neutral state in which a clutch (30) is disconnected from the driving force transmitter of the engine at idle to a non-neutral state in which the clutch is connected to the driving force transmitter, and a controller (7) configured or programmed to perform a control to reduce a rotation speed of the engine by regeneration of the generator based on a user's switching operation on a shift operator (L) to switch the outboard motor from the neutral state to the non-neutral state, and then connect the clutch to the driving force transmitter while rotating the engine.

摘要： A marine propulsion system (102, 202, 302) includes an outboard motor (102a, 302a) installed on a hull (101) and including an engine (1) configured to drive a propulsion generator, and a generator (5) configured to generate power by driving of the engine, a capacitor (7) provided in the outboard motor and configured to smooth the power generated by the generator and output the smoothed power to a device on a hull side (H), and a power distributor (8, 308) provided in the outboard motor and configured to limit an output from the capacitor to the device on the hull side.
