• 3 Blades---The new aluminum alloy prfor Opeller has 3 sharp blades, and the blade section has almost zero resistance when prfor Opelling underwater, which can quickly cut through the water and advance forward. 14 Teeth--- The connection of the prfor Opeller blades is linked by 14 spline teeth. The spline teeth are forged from high density pure copper, which can better match the speed of the engine, so that your ship can move faster. Salt Resistant--- The surface of the prfor Opeller has been painted and brushed, the surface is extremely smooth and clean, and has the characteristics of salt resistance and long‑term durability. Even if it is immersed in seawater for a long time, the prfor Opeller blade will not be damaged. Prop Size---9.25in diameter (23.5cm) x 11in / 28cm pitch, positive pitch benefits from normal bow lift allowing the use of larger diameter prfor Opellers, while negative pitch provides additional blade strength for very high speed applications.Cupped blades are a technology used to improve prfor Opeller performance under specific conditions. Cupped prfor Opeller will exhibit very high efficiency at high speeds and minimize cavitation under heavy loads.
