We ran them on a 35 Fountain with blower motors. Plane faster, cruise faster than a 4 blade at the same rpm by about 3-4 mph over the Q-4 Hydro. They ran about 4 mph slower on the top end than the Q-4 Hydro. Tom at Hydromotive said they could blue print and modify them to run the same on the top end. I think were they really make a difference is with a very high X were the props are surfacing. Just depends on what you are looking for.
