An O.S. Safety Propeller Locknut assembly prevents the propeller from being thrown - even if it becomes loose in operation. Particularly suitable for medium to larger four strokes and essential for engines that are prone to kicking the prop free due to a backfire. Supplied as standard with all O.S. four strokes from .70 cu.in. capacity and up.
