Abstract:

A variable pitch propeller apparatus for use with a motor is disclosed. The apparatus includes a housing having a plurality of blades mounted therein for rotation. Adjustable high pitch and low pitch stop rings are connected to the housing and a synchronizer ring is slidably received by the housing and positioned between the stop rings. The synchronizer ring is limited in movement by the desired position of the adjustable high pitch stop ring and adjustable low pitch stop ring. A plurality of springs are used to bias the blades in a low pitch position for trolling and when the spring force is overcome by the thrust on the blades, the blades pivot to a high pitch position. The springs are cooperatively connected to the synchronizer ring or to the blades so that blade movement is coordinated and simultaneous. A tensioning ring is connected to the housing for simultaneously adjusting the tension on the springs.
