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 which are drivingly connected, and an outer shaft arranged coaxially with and radially outside of the propeller shaft. The outer shaft is drivingly connected to one or more propeller blades for varying the pitch angle, and the propeller shaft is drivingly fixed to one of the planetary gear members and another one of the planetary gear members is arranged to drive the outer shaft by a driving torque exerted on the propeller shaft. The propeller drive arrangement has a pitch controlling member for varying the pitch angle of the one or more propeller blades, in a first state, to rotationally fix the third planetary gear member to the second planetary gear member so that the propeller shaft and the outer shaft are arranged to rotate with the same rotational speed, and, in a second state, to engage the third planetary gear member to a housing so that the third planetary gear member is rotationally fixed with respect to the housing.
