Used the prop selector which suggested this prop in the list. I wanted a 4 blade prop to help eliminate a slight cavitation problem, as well as pick up some speed but I also boat at lakes in excess of 6,500 feet in elevation. The prop is wonderful! it came quickly, was well packaged, and looked like a quality product. I've used Solas props before with good success. Cavitation issue gone completely. acceleration is very good, control is better than a 3 blade. top end speed at WOT was 5400RPM 43mph. Nice! great performance with 6 adults in the boat 6,700 feet elevation 5,200 RPM, 39MPH
