15 1/4 X 15 A3R PROP VORTEX propellers are high-performance aluminum with the XHS exchangeable Hub System, high-performance blade geometry, precision-balanced blades, and a high-gloss powder finish. Vortex propellers are a perfect 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 3-blade propellers have been created for better holeshots without sacrificing top-end performance. A decreased diameter helps maintain top-end speed, while a revised, aggressive blade geometry mixes with an additional cup for peak acceleration and grip. Key Features: Right-hand rotation direction. Blades with a good balance. A propeller with three blades. Blade thickness that is optimal for maximum performance and longevity. Powder paint with a high gloss finish For strength and durability, use a high-quality aluminum alloy. It is compatible with both the engine's characteristics and the drive's hydrodynamics. It improves overall efficiency by lowering fuel consumption. Product Details: SKU: 992002 UPC: 014984010283 Weight: 8.00 LBS PITCH: 15 MATERIAL: Aluminum 3 & 4-Blade
