A propeller comprising a main body (1 ) which is suitable to be fixed to a propeller shaft (2) of a vessel to rotate about a longitudinal axis (A) and which supports a plurality of blades (3) which protrude from the main body (1 ), wherein the blades (3) can rotate with respect to the main body (1 ) around a radial axis (R), wherein a hub (12) suitable to be keyed to the propeller shaft (2) is connected to the blades (3) by means of a mechanical transmission (17, 18) so that a relative rotation of the hub (12) with respect to the main body (1 ) around the longitudinal axis (A) can cause a rotation of the blades (3) around their radial axis (R) from a first position of the blades (3) to a second position of the blades (3), wherein the hub (12) comprises a first sleeve (22) which is mechanically coupled with a second sleeve (26) by outer profiles (27, 28), wherein elastic means (29, 29', 29") urge the sleeves (22, 26) against each other towards at least two substantially stable positions of the sleeves (22, 26) in the their reciprocal rotation, which substantially stable positions correspond to the first position of the blades (3) and to a third position of the blades (3).
