3-Bladed v. 4-Bladed Propellers

For years, three-blade propellers have been the standard issue for virtually all boat motors. But on certain boats, particularly bigger ones, a four-blade propeller can offer some distinct advantages, so their usage is becoming more and more common. Although three-blade propellers will be faster at full throttle, most of the time four-blade propellers are more stable and efficient, meaning you spend less on gas and outboard motor oil.

The overall increased surface area of the blades on a four-blade prop make planing easier, which is particularly useful when you are pulling skiers or wakeboarders. This large amount of blade area also reduces vibrations, making for a smoother ride on all levels. There is no cut-and-dry method for choosing which propeller is best for your vessel; there are simply too many variables in the equation.
