Feature: 1. The superior quality outboard propeller is a perfect replacement for BF 35HP 1991‑1994 and so on to better and accurately meet your demands. 2. The 3 sharp blades can cut the water surface fast and advance forward, and the resistance of the blade is almost zero when propelled underwater. 3. The connection is made of pure copper with 13 spline teeth to better match the engine speed, helping your outboard to charge faster on the water. 4. The higher rake angle tightens the vortex generated by the propeller increases the lift and overall performance of the ship, minimizes slippage and improves performance and fuel economy. 5. The surface has been painted, very smooth and clean, very hard, salt‑resistant, corrosion‑resistant and durable. Not easy to be damaged even if soaked in sea water for a long time.
