A propeller drive arrangement includes a propeller shaft, a planetary gear comprising a first planetary gear member, a second planetary gear member and a third planetary gear member, an outer shaft arranged coaxially with and radially outside of the propeller shaft, A gear wheel set drivingly connecting the second planetary gear member with the outer shaft, The outer shaft is drivingly connected to the one or more propeller blades for varying the pitch angle.The propeller shaft is drivingly fixed to the first planetary gear member, and the second planetary gear member drives the outer shaft via the gear wheel set by a driving torque exerted on the propeller shaft. A pitch controlling actuator controls the pitch angle of the one or more propeller blades,to, in a first state, engage the third planetary gear member to a housing so that the propeller shaft and the outer shaft are arranged to rotate with the same rotational speed, and, in a second state, actuate the third planetary gear member so that the third planetary gear member rotates with respect to the housing.
