Turning Point Propellers: Hub Kits & Propeller Accessories Built to Perform

When it comes to keeping a marine propulsion system running at peak efficiency, the supporting hardware matters just as much as the propeller itself. Turning Point Propellers has spent over two decades engineering not only industry-leading prop designs, but also the accessories and parts ecosystem that surrounds them — from hub kits to replacement components that keep boaters on the water longer and with less hassle.

The MasterGuard Hub System: A Game-Changer in Prop Accessories

Perhaps the most significant innovation Turning Point brings to the Propeller Parts & Accessories category is its MasterGuard Hub Kit System. Turning Point was the first to introduce the interchangeable hub system to the market, and the design remains a benchmark for protection and versatility. The hub sits between the propeller housing and the engine shaft, and its job is critical: absorbing shift shock, impact shock, and damaging vibrations before they reach the lower unit.

What makes Turning Point's hub kits stand apart from the competition is their patented one-piece construction featuring glass-filled nylon over brass splines. This approach eliminates the weak points commonly found in multi-part “sleeve and spline” designs and pressed-in rubber hub systems. The glass-reinforced polymer construction eliminates vibration and chatter while reducing gear shock and potential engine drive damage — a meaningful advantage for any serious boater.

Lifetime Warranty Hubs & Cross-Brand Compatibility

Turning Point's MasterGuard Series hubs carry the industry's only Lifetime Warranty, a testament to the confidence the brand places in its engineering. Beyond the warranty, these hub kits are designed with broad compatibility in mind: Turning Point's 500 and 700 series hub kits interchange with other manufacturers' propellers and are direct upgrades for Mercury® Flo-Torq II®, Michigan Wheel XHS®, and Solas® Rubex™ hub kit systems. This cross-compatibility means boaters can often save significantly when replacing just the prop housing rather than the entire assembly — up to 38% on a replacement propeller housing when the lifetime hub is already on board.

Next-Generation Sound Dampening: The MasterTorq 800 Series

For boaters running high-horsepower setups, Turning Point also offers the MasterTorq™ 800 Series SDH™ Sound Dampening Hub, a next-generation hybrid hub that blends advanced materials to reduce noise and vibration at the drivetrain level. These kits are engineered for demanding applications and represent the cutting edge of what propeller accessory technology can deliver.

Field-Serviceable by Design

One practical advantage of the Turning Point hub-and-housing system is that it is field-serviceable. If a propeller strikes an object, boaters can often replace just the hub insert rather than the entire prop assembly, dramatically reducing the cost of impact damage. This modular philosophy — where the hub kit and propeller housing are separate, interchangeable components — means that investing in a quality Turning Point hub kit pays dividends over the long life of a boat.

Whether you are sourcing a replacement hub kit for a Hustler aluminum prop, an Express Mach3 or Mach4 stainless housing, or a specialty accessory to round out your propulsion setup, Turning Point's propeller parts and accessories lineup is engineered with the same precision and durability the brand is known for across its entire product range.
