The Vevor outboard propeller is a 4-blade aluminum replacement prop designed for selected Mercury and Mariner 135-300 HP outboard engines with a 4-3/4" gearcase. Its 14" diameter and 19" pitch are built to provide stable thrust, strong water grip, and smooth control at cruising speeds. The corrosion-resistant aluminum alloy construction is suited for both freshwater and saltwater use. An included M21 interchangeable hub kit helps simplify installation and secure fitment. The internal rubber hub is designed to reduce vibration, noise, and shock loads during operation.
