Abstract

A vessel propulsion device transmits a drive force of an engine to a propulsive force generator. The vessel propulsion device includes a generator that is driven by the engine, a power shutoff detector that detects a power shutoff state in which the drive force of the engine is not transmitted to the propulsive force generator, and a controller configured or programmed to, when the power shutoff detector detects the power shutoff state, select one of a plurality of charging modes to charge a battery connected to the generator and control a target speed of the engine based on a selected one of the charging modes.
