A folding blade propeller for a power vessel wherein the blades (1, 2) are synchronized in their pivotal movement as they pivot from one position to the other by flexible links (20a, 20b). The flexible links are connected at one end thereof to the base (8) of one propeller blade (1) and at the opposite to the base (9) of another (2) and act as pulling members. When one blade (1) pivots the flexible link (20a, 20b) pulls on the base of the other blade (2) to which it is attached to simultaneously pivot that blade. Slack in the links is minimized by having each link in rolling contact with rounded surfaces (8a, 9a) on the base of the respective propeller blades that are interconnected by that link.
