Turning Point 505 Interchangeable Propeller Hub Kit

The Turning Point 505 hub kit connects a compatible interchangeable propeller to the matching engine shaft. Its splined inner connection is designed around the engine, while the outer assembly interfaces with the selected propeller housing. This separation allows a propeller to be changed without replacing every part of the hub system. Brass splines and other corrosion-resistant materials are part of the stated kit construction.

Turning Point designs its interchangeable hub system to cushion engagement shock and limit vibration transmitted through the drive. The manufacturer also identifies the system as compatible with selected Michigan Wheel XHS and Mercury Flo-Torq interchangeable propeller arrangements. Those references describe a system family, not an assurance that kit 505 fits every engine using those brands. Use the Turning Point fitment guide to match this particular kit number to the shaft and propeller before purchase.

The hub kit is useful when fitting a replacement propeller housing to an outboard or sterndrive requiring the 505 installation configuration. Inspect the existing shaft splines and propeller hardware before assembly, then follow the kit’s installation directions. A propeller housing is a separate item and must match the chosen hub system.
