1、Application: Replacement for Suzuki 8‑20HP. Boat motor propeller is designed based on OEM blade geometry with proper cupping and camber added. Excellent bow lift, acceleration and top speed plus reduced slip and increased bite. 2、Low Resistance: The aluminum alloy propeller blade has three sharp blades, and the blade section is subject to almost zero resistance when propelling underwater, which can quickly cut the water surface and advance forward. 3、10 Spline Teeth: The connection of the propeller blade is linked by 10 spline teeth. The spline teeth are forged from high density pure copper, which can better match the speed of the engine, so that your outboard can be faster on the water. 4、Salt and Rust Resistance: The propeller forged by high density aluminum alloy has been painted and brushed, the surface is smooth and clean, salt and rust resistance, even if it is immersed in seawater for a long time, the propeller blade will not be damaged. 5、Good Propulsion Performance: After a long time of use, the propeller blades will become more and more smooth and bright, which can be very good to replace or repair the original damaged and worn out propeller blades, and better propulsion performance for your outboard engine.
