An outboard motor power generation system includes an engine, a power generator, a converting device configured to convert alternating-current power into direct-current power, an engine cover configured to cover the engine, the power generator, and the converting device, a battery, and a transformer provided on an electric pathway between the converting device and the battery and configured to raise the voltage of the direct-current power output from the converting device relative to the charge voltage of the battery.

Outboard motor power generation system and outboard motor

A marine propulsion device, including an engine including a crankshaft, and a power generator including a rotor configured to be rotated by the crankshaft, and a stator arranged to face the rotor, the stator including a first coil group and a second coil group each configured to generate alternating current (AC), the second coil group being configured to generate more electric power than the first coil group. The marine propulsion device further includes a rectifier configured to rectify the AC generated by the first coil group to thereby obtain a first direct current (DC), and to output the first DC to a first battery, a converting device configured to convert the AC generated by the second coil group into a second DC, and a transformation device configured to transform a voltage of the second DC, and to output the voltage-transformed DC to a second battery.
