Abstract
A marine propulsion system includes an outboard motor installed on a hull and including an engine to drive a propulsion generator, and a generator to generate power by driving of the engine, a capacitor provided in the outboard motor to smooth the power generated by the generator and output the smoothed power to a device on a hull side, and a power distributor provided in the outboard motor to limit an output from the capacitor to the device on the hull side.

A marine propulsion system comprising:
- an outboard motor installed on a hull and including an engine to drive a propulsion generator, and a generator to generate power by driving of the engine;
- a capacitor provided in the outboard motor to smooth the power generated by the generator and output the smoothed power to a device on a hull side;
- a power distributor provided in the outboard motor to limit an output from the capacitor to the device on the hull side based on the device on the hull side being in an overload state in which power equal to or higher than a first threshold is consumed;
- and
- a charge control circuit to perform a control to limit a supply of power from the generator to the capacitor to charge the capacitor based on the device on the hull side being in a low load state in which power less than a second threshold that is smaller than the first threshold is consumed.
