I've had 13 pitch 3 blade and 11 pitch 4 blade. Problem was with me and a large buddy in the boat it wouldn't plane out. Plowed water at 11 to 14 mph. This prop has been the best so far at getting up and going. It is not as fast as the 13 pitch but it will take everything you can put in the boat to 25 mph (to 28 by myself). Smooth easy steering love this prop going to get a stainless version.
