The invention relates to a method for the operation of a marine propeller (1) comprising the following steps: - detection, by means of a sensor (11), of noise on a solid body (1, 4, 8) caused by gas cavitation and/or pseudocavitation, - transmission of a measurement signal of the sensor (11) by means of a contactless transmission method from the sensor (11) to a signal processing unit, and - generation of control commands by the signal processing unit depending on the received measurement signal to change the propeller speed by means a drive motor and/or to change the angle of attack of the blade of the marine propeller (1) by means of an actuator.
