After pricing props in local shops, decided to take a chance on the VEVOR prop and ordered two to have a spare. Installed on a 20' deck boat with a 115hp Evinrude and have used it on several trips now and it works great. Does not cavitate on sharp turns at full speed and grips the water very well. Blade tips are cupped for more push which pulls down engine on take off slightly but gained a couple mph top speed. Excellent value.
