Feature: 1. Aluminum alloy propeller, with three sharp blades, can quickly cut through the water and push forward, the blade profile is subjected to almost zero drag during underwater propulsion. 2. The higher rake angle tights the vortex produced by the propellers that increase the boat lift and overall performance, improves maneuvering and boat's lift through positive rake and cupping. 3. Tuned progressive pitch angles accelerate and channel water to minimize slip and increase performance and fuel economy. 4. The propeller blade connection is made of pure copper 10 spline teeth to better match the engine speed, so that your outboard engine can be faster on the water. 5. The surface has been painted, very smooth and clean, very hard, salt and decay resistant and durable, with the passage of time becomes more and more strong, the blade will be more and more smooth and beautiful. 6. This is a very good market replacement, can replace or repair the original damaged old propeller blade, better propulsion performance for your outboard engine.
