Outboard Propeller, Upgrade OEM 15 Spline Tooth Aluminum Outboard Boat Propeller Fit Yamaha Engines 50-130 HP, 4-1/4" Gearcase, 3-Blade, RH (Right Hand Rotation), OEM Parts No. 6E5-45945-01-EL

About these items Reliable Outboard Engine Compatibility These outboard propellers are designed for selected Mercury Mariner and Yamaha engines with horsepower ranges from 40 HP up to 400 HP depending on the model. Each propeller supports right-hand rotation and fits specific gearcase sizes such as 4-1/4' or 4-3/4'. The precise design allows the propeller to serve as a direct replacement for compatible engines while maintaining proper performance and balance during operation. Durable Aluminum Alloy Construction Manufactured from high-strength corrosion-resistant aluminum alloy, these boat propellers are built to withstand demanding marine environments. The lightweight yet strong construction helps improve rotational efficiency while resisting corrosion from saltwater and freshwater exposure. This durable material supports long service life and reliable performance for frequent boating use. Powerful Thrust and Efficient Performance With various diameter and pitch combinations including 13' * 19', 13-1/4' * 17', 13-1/2' * 15', 14' * 11', and 14-1/4' * 21', these propellers provide optimized thrust for different boating needs. Some models are designed for faster acceleration and heavy loads, while others deliver higher top speeds and improved fuel efficiency. The balanced blade design enhances propulsion efficiency and smooth water flow. Smooth Operation with Reduced Vibration Each propeller features an internal rubber hub that helps absorb shock loads from the engine and water resistance. This cushioning effect reduces vibration and noise during operation while protecting the engine drivetrain. The balanced blade structure contributes to smoother boating performance and stable propulsion at various speeds. Easy Installation and Secure Fit The propellers are designed for quick installation using either an M21 interchangeable hub kit or press-in hub system depending on the model. The hub components ensure a secure connection between the propeller and the engine drive shaft. Installation hardware such as thrust washers sleeves nuts or cotter pins is included to simplify replacement and ensure reliable mounting.
