A method for controlling a marine propulsion device having an engine rotatably engaged with a transmission via a clutch, and rotatably engaged with a charging device for charging a battery. The method includes measuring a voltage of the battery and comparing the voltage to a minimum threshold. The method further includes increasing a speed of the engine when the voltage is below the minimum threshold, and also increasing a slip of the clutch when the speed of the engine is increased in response to the voltage being below the minimum threshold.
