Turning Point MasterGuard Propeller Installation Kit 503

Heavy Duty MasterGuard Propeller Hub Kit for 4.25 and 4.75 Gearcases

This propeller hub installation kit is engineered to provide long term durability, enhanced lower unit protection, and maximum value for boaters running compatible outboard and sterndrive engines. Designed for engines with 4.25 inch or 4.75 inch gearcases, the MasterGuard hub system uses a patented one piece construction to reduce vibration, absorb shock, and prevent common hub failures. The combination of corrosion resistant marine bronze splines and over molded glass filled nylon improves reliability while allowing the hub to be reused after most prop strikes. Backed by a lifetime warranty for qualifying consumer use, this system helps reduce propeller replacement costs by allowing the purchase of prop housings only.
