Turning Point Propellers Hub Kit 21 (Part 11200100) for Mercury, Mariner and Force Outboards 9.9-25 HP

The Turning Point Propellers Hub Kit 21, part number 11200100, is a replacement propeller hub system designed to restore the connection between the engine's drive shaft splines and the propeller. The inner splines of the hub adapt directly to the engine, while the outer hub is compatible with different propellers, letting an owner change props without buying a new hub each time. This can reduce the cost of switching propellers since the existing hub kit is reused across compatible props.

Hub Kit 21 is built with brass splines for corrosion resistance in marine environments. A properly seated hub kit absorbs shifting shock between the gearcase and the propeller, which helps reduce gear shock and engine or drive damage, and helps eliminate propeller vibration, chatter, hub cracking, and hub failure over time.

This hub kit is designed for a 10 spline propeller shaft configuration. It fits Force 25hp outboards ('95-'98), and Mercury and Mariner outboards including the 9.9 Bigfoot, 15hp Bigfoot, 18hp ('80-'85), 20hp ('86 and newer), and 25hp 2 stroke ('85 and newer). It is backed by a lifetime warranty.
