OS Engine Locknut Set FS40/48/52 Surpass X-OS45810100

OS Engine Locknut Set FS40/48/52 Surpass 45810100

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. 

Fits 40S 48S 52S and others
