A folding propeller (1) with an adjustable rake angle has a hub (10) and at least three propeller blades (11) which are pivotally mounted in the hub (10) about pivot axes (25a) extending radially outwards from a central area in the hub (10), for the propeller blades (11) to unfolded and fold between radially protruding operating positions, and are rearwardly extending passive position with respective rear edges of the propeller blades facing each other. The propeller blades (11) are adapted to pass each other in said passive position to be movable to both sides from the passive position to an operating position. An abutment (30) is defining in forward propulsion the rake angle of the propeller blades (11).
