This revolutionary production process almost eliminates gaps, pockets, and air bubbles in the propeller material, yielding a grain structure that is much tighter than a typical die-cast procedure. The squeeze cast process produces a tight grain structure and higher density. To prevent propeller slippage and blowout in bends while increasing peak speed and fuel economy, a thinner blade with sharply curled cupped and trailing edges can be used. Due to the same race-proven construction as Turning Point's stainless steel propellers, the Hustler aluminum propellers resist blade flex and give better fuel economy and performance. Key Features: Propeller blades are less prone to flexing, resulting in increased fuel efficiency and performance. Outboard boat engines ranging from 2.5 hp to more than 100 hp within models. Squeeze casting increases the strength, performance, and repairability of the product. It is protected with a five-step powder-coat finish. Die-casting of aluminum is of high quality and Durable. High-Quality and more efficient blades. Product Details: SKU: 011025 UPC: 014984005388 Weight: 9.68 LBS MATERIAL: Aluminum PITCH: 19
