This aluminum outboard propeller is designed for selected Yamaha 50-130 HP engines with a 4-1/4" gearcase and right-hand rotation. Its 3-blade design with a 14" diameter and 11" pitch is optimized for strong low-torque thrust, helping with quick starts and heavier loads. The high-strength aluminum alloy construction resists corrosion, impact, and bending for dependable use in freshwater and saltwater conditions. An internal rubber hub helps reduce vibration and noise while cushioning shock loads to protect the drivetrain. The press-in hub design supports straightforward replacement using your existing washer and nut.
