Abstract
To maintain stabilized operation of a boat engine, a propulsion device may be provided with two separate batteries for different uses in case one of the batteries suffers a voltage drop. A power source device is provided with a propulsion battery for supplying power to engine-related components of an outboard motor and an auxiliary battery for supplying power to boat accessories. An anomaly time power supply circuit is connected to the power supply route of the propulsion battery and the power supply route of the auxiliary battery. Electric power from the auxiliary battery is supplied to the engine-related components when the charged voltage of the propulsion battery lowers below the charged voltage of the auxiliary battery, so that power to the engine-related components is supplemented in order to maintain stabilized operation of the engine.
