The prop selection icon on the AiBoats website gives erroneous information on some motors. I have a 20 H.P., 1973 Mercury 2-stroke. When this information is entered into the prop selection criteria, all of the props suggested on the website are all 3-blade props. This is incorrect. This motor was shipped from the factory with a 2-blade, 11 pitch aluminum prop. I bought this motor used, with a 3-blade prop. When I switched to the factory-recommended 2-blade prop, speed at full throttle increased by 12 mph. This little motor drives a 14' aluminum Valco boat and with the 2--blade prop, it will put the boat on full plane and gives just over 30 mph.
