1. A method for controlling a marine propulsion device to have sufficient power available within a power system to meet demands, the marine propulsion device having an engine rotatably engaged with a transmission via a clutch, the method comprising:
measuring the power available within the power system;
measuring the demand for power on the power system;
determining a power difference between the demand and the power available within the power system, and comparing the power difference to a minimum threshold; and
increasing a speed of the engine and increasing a slip of the clutch when the power difference exceeds the minimum threshold.
