A marine propeller includes a series of releasably affixed blades which allow pitch adjustment. The blades are each secured to different blade disks which are positioned in hub wells and held by positioning pins. The method describes how the blades, which are each attached to blade disks at preselected positions can be released, rotated and reaffixed. The disk can then be rotated in the opposite direction on the hub in a smaller increment, to provide more or less pitch as needed.
