Is a 3 or 4 blade prop faster?
Higher Top Speed By stripping the extra blade, there’s less drag on a 3-blade propeller. Less drag equates to a higher top speed since there’s less slowing down the boat. If sheer speed is your cup of tea, the best option is to go for the fewest blades on your propeller. Higher Pitch: Propellers with higher pitch are generally suited for boats that operate at higher speeds, such as speedboats and performance-oriented vessels. They perform well in open water and calmer conditions where top speed is more important than rapid acceleration.
