The Vevor outboard propeller is a direct-replacement aluminum propeller designed for selected Yamaha 60-130 HP outboard engines with a 4-1/4" gearcase and right-hand rotation. Its 3-blade design with a 13-1/2" diameter and 15" pitch delivers responsive acceleration, steady thrust, and efficient everyday performance. Made from high-strength aluminum alloy, it is built to resist corrosion and handle both freshwater and saltwater use. The press-in hub design supports straightforward installation using your existing washer and nut. An internal rubber hub helps reduce vibration, noise, and shock loads during operation.
