Abstract
A marine propeller assembly which folds completely parallel to a drive shaft axis when the boat motor is disengaged is disclosed. When the boat motor is disengaged the propeller blades fold rearward due to the force caused by the moving water under the boat. When the boat motor is engaged and the drive shaft beings to rotate, the centrifugal force causes the propeller blades to extend out 90 degrees to the drive shaft.
