3 Blade or 4 Blade Prop

With modern designs, either 3-blade props or 4-blade props can be excellent all-around performers. Three-blade propellers are popular because they tend to provide a good blend of acceleration, fuel efficiency, life, and speed. Four-blade propellers can improve acceleration, fuel efficiency, or lift, but were often considered slower. However, improvements in design engineering of modern 4-blade props have really negated that issue.

Which type of propeller depends more on what is best for your specific boat and motor as well as the type(s) of boating you do and what performance factors are most important to you. For example, 4-blade props can provide increased water displacement capability, lift, and grip, which can enhance handling and fuel efficiency among other factors. Even with improved designs, though, the addition of the fourth prop does create additional drag and can reduce top speed.
