Turning Point MasterGuard Propeller Installation Kit 501

MasterGuard Propeller Hub Kit for 4.25 and 4.75 Gearcase Engines

This propeller hub installation kit is designed to deliver long lasting performance, lower unit protection, and cost savings for a wide range of outboard and sterndrive engines. Built for engines with 4.25 inch or 4.75 inch gearcases, the MasterGuard system uses a patented one piece hub design to reduce vibration, absorb shock, and prevent common hub failures. Constructed with durable marine bronze splines and over molded glass filled nylon, the hub is engineered to withstand normal wear while remaining reusable after most prop strikes. Backed by a lifetime warranty for qualifying consumer use, this system allows boaters to replace only the propeller housing when needed, helping reduce long term ownership costs.
