The A3R PROP VORTEX propellers are made of high-performance aluminum and include the XHS Exchangeable Hub System, high-performance blade geometry, flawlessly balanced blades, and a high-gloss powder finish. Vortex propellers are a fantastic alternative for a replacement or spare propeller and are available for a wide variety of applications (9.9 HP through V6/V8 Outboard and Sterndrive). We've expanded our new Vortex 3-blade outboard propeller series in response to popular demand. The new Vortex blade propellers are made to improve holeshot without sacrificing top-end speed. A revised, aggressive blade design combines with an additional cup for maximum acceleration and grip, while a smaller diameter aids top-end speed. Key Features: Rotation in the right direction. Propeller with three blades. Well-balanced blades. The powder coat is a high-gloss black. For strength and durability, use a high-quality aluminum alloy. It is compatible with the engine's characteristics and the hydrodynamics of the drive. It improves overall efficiency by lowering fuel consumption.
