Boat Propeller Hub Kits

A propeller hub is a crucial component that connects a prop to its driveshaft and transfers the torque created by the engine. Besides, the hub is designed to work as a shock absorber when the propeller hits something underwater, which helps to avoid serious damage to the powertrain. In the 1940s, the shear-pin hub system was spread, with a breakable pin acting as a sacrificial component when the prop gets blocked. Throughout the decades of evolution, however, the construction of hub assembly was drastically improved to withstand higher torque.

More modern designs use a rubber or plastic inner sleeve, or more complex cushioning construction reinforced with high-tech polymers, and many solutions applied there are aimed at greater reliability, simplified installation, and longer lifespan. Some models even allow you to use the same hub system after replacing a damaged propeller! A large assortment of boat propeller hub kits is available on our virtual shelves, along with hub sleeves and bushings. Sourced from such reputable brands as Turning Point, SOLAS Propellers, and Michigan Wheel, these are high-quality products designed for many engine makes including Johnson/Evinrude, Mariner, Volvo Penta, Yamaha, and lots of others.
