The 6100/6000 motor and power supply are not rated to handle the higher wattage needed for the 6200 propeller, it will eventually cause the power supply to fail for sure and possibly the motor. A 6200 prop needs 60W, a 6000 transformer can only deliver 20W and a 6100 transformer is maxed out at 60W. The true 6200 transformer could handle 80W to have some extra capacity for jammed pumps.
