A computer implemented diagnostics system for a marine propeller drive unit is provided. The diagnostics system comprising processing circuitry connected to a speed sensor system and to a control unit associated with the electric machine. The speed sensor system is arranged in connection to the differential arrangement to provide propeller speed data to the processing circuitry indicative of a speed of rotation of at least one of the propeller axles of the self-balancing propeller drive unit. The control unit is arranged to provide motor current data to the processing circuitry indicative of a motor current drawn by the electric machine. The processing circuitry is arranged to monitor the motor current data from the control unit, and the propeller speed data from the speed sensor system, and to classify a state of the self-balancing propeller drive unit into a pre-determined number of states comprising one or more fault states, based on the motor current data and on the propeller speed data. The processing circuitry is arranged to trigger an action by the diagnostics system in case the state of the self-balancing propeller drive unit is classified as a fault state.
