I purchased this for a lehr 9.9 (also will work on yamaha or parsun outboards) that was on a 10ft rib to try and get the boat to plane with 2 people. It didn't work (needs not power) but at least the motor is not really bogged down with this prop. On the prop itself it has a lot thicker blades than the original and overall looks to be of great quality. Also Deep Blue Yacht Supply was the cheapest place I could find the prop and they where very quick to get the order shipped.
