This unique manufacturing process practically eliminates gaps, pockets, and air bubbles in the propeller material, resulting in a grain structure that is much tighter than that of a traditional die-cast procedure. Aluminum propellers are more resistant to blade flex, resulting in better fuel efficiency and performance. Exhaust valves in the prop barrel have been fine-tuned to reduce the amount of water around the blades during acceleration, resulting in faster hole shots and greater horsepower. A five-step powder-coated finish protects Hustler aluminum propellers. No other propeller on the market today compares to an aluminum propeller in terms of performance, longevity, and value. Key Features: A powder-coated robotically with AkzoNobel's unique anti-corrosive coating powder. Outstanding peak speed and acceleration. Squeeze casting improves strength, performance, and repairability. A five-step powder-coating finish protects aluminum propellers. Aluminum propellers are more resistant to blade flex, resulting in better fuel efficiency and performance. Aluminum propeller Blades that are stronger and perform better. It's much more important that it's safe for the environment. Product Details: SKU: 011009 UPC: 014984000093 Weight: 13.83 LBS MATERIAL: Aluminum Diameter: 14.25 PITCH: 21
