Turning Point MasterGuard Propeller Installation Kit 504

MasterGuard Propeller Hub Installation Kit for 4.25 and 4.75 Gearcases

This propeller installation kit is engineered to provide maximum protection, performance, and long term value for outboard and sterndrive engines. Designed for engines with 4.25 inch or 4.75 inch gearcases, the MasterGuard hub system helps reduce gear shock, absorb vibration, and protect the lower unit during normal boating use. The one piece hub design combines durable marine bronze splines with over molded glass filled nylon to eliminate common hub failures found in multi part systems. Backed by an industry leading lifetime warranty, this system helps boaters save significantly on future propeller replacements by allowing reuse of the hub after most prop strikes.
