A marine propulsor, comprising: a stationary part and a movable part which is movable relative to the stationary part; and a wireless communication system, comprising at least one transmitter which is disposed in the movable part and is configured to transmit an electromagnetic data signal and at least one receiver which is disposed in the stationary part and is configured to receive the electromagnetic data signal; characterized in that the wireless communication system includes a diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver, the wireless communication system being configured to: establish a data signal between the at least one transmitter and the at least one receiver; determine whether the data signal quality and/or strength are within defined limits; if the data signal quality and/or strength are not within the defined limits, increase or decrease transmission power in order to bring the data signal quality and/or strength within the defined limits; if the data signal quality and/or strength are still not within the defined limits, adopt the diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver in order to bring the data signal quality and/or strength within the defined limits; and if the data signal quality and/or strength are within the defined limits, decrease transmission power to a minimum level required to maintain the data signal quality and/or strength within the defined limits. a stationary part and a movable part which is movable relative to the stationary part; and a wireless communication system, comprising at least one transmitter which is disposed in the movable part and is configured to transmit an electromagnetic data signal and at least one receiver which is disposed in the stationary part and is configured to receive the electromagnetic data signal; characterized in that the wireless communication system includes a diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver, the wireless communication system being configured to: establish a data signal between the at least one transmitter and the at least one receiver; determine whether the data signal quality and/or strength are within defined limits; if the data signal quality and/or strength are not within the defined limits, increase or decrease transmission power in order to bring the data signal quality and/or strength within the defined limits; if the data signal quality and/or strength are still not within the defined limits, adopt the diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver in order to bring the data signal quality and/or strength within the defined limits; and if the data signal quality and/or strength are within the defined limits, decrease transmission power to a minimum level required to maintain the data signal quality and/or strength within the defined limits. establish a data signal between the at least one transmitter and the at least one receiver; determine whether the data signal quality and/or strength are within defined limits; if the data signal quality and/or strength are not within the defined limits, increase or decrease transmission power in order to bring the data signal quality and/or strength within the defined limits; if the data signal quality and/or strength are still not within the defined limits, adopt the diversity scheme for mitigating multipath distortion of the electromagnetic data signal between the at least one transmitter and the at least one receiver in order to bring the data signal quality and/or strength within the defined limits; and if the data signal quality and/or strength are within the defined limits, decrease transmission power to a minimum level required to maintain the data signal quality and/or strength within the defined limits.
