Turning Point Hub Kit #510

The Turning Point Hub Kit #510 is the propeller hub system engineered for Volvo Penta AQ-series inboard engines—the workhorse of recreational and professional boating. Whether you're running an AQ200, AQ250, AQ270, AQ280, or AQ290, this hub kit addresses a critical weak point in drivetrain durability: the connection between engine shaft and propeller. After years on the water, any boater knows that shock load from hard acceleration, cavitation events, or blade impact can fracture standard hub designs, leaving you stranded. The Turning Point Hub Kit #510 eliminates that risk with a lifetime warranty and a design that truly eliminates repeat purchases.

The innovation lies in the dual-spline architecture: inner splines adapt precisely to your specific Volvo engine shaft, while the outer hub accepts any compatible Turning Point propeller without modification. This modular approach means you can swap props for different conditions—cruising pitch for fuel economy, aggressive pitch for watersports—without touching the hub itself. The engineered elastomer insert dampens gear shock and absorbs vibration that would otherwise transmit directly to the engine block and transmission, reducing fatigue cracking and bearing wear. At just 1.5 lbs, the compact 3×3×6-inch form factor integrates seamlessly into existing Volvo AQ installations with no additional fabrication required.

This hub kit is indispensable for operators who demand reliability in saltwater, high-load, or high-hour service environments. Commercial guides, charter captains, and serious recreational boaters benefit most from the shock-absorption technology, which extends drivetrain life by thousands of hours. Installation is straightforward on any Volvo AQ200–AQ290 equipped vessel; no special tools or expertise required. The lifetime warranty reflects Turning Point's confidence in durability—a guarantee that justifies the investment for anyone serious about avoiding mid-season mechanical failures.
