Undoubtedly, three-blade propellers are those more commonly used in boats. Their performance is usually very good in all sectors, they normally achieve higher final speeds, they are available in a bigger variety of diameter-pitch sizes and their cost is lower.

However, throughout the past years, the usage of four-blade propellers has entered into a continuous struggle of improving the performance of our boat, and, of course, this was not coincidental. It is evidenced that four-blade propellers usually increase the engine's load, but the production of more and more powerful engines has opened the way for their use.
