How to Choose the Right Blades for Your Piranha Propeller

Once you select your hub, you'll be able to choose from a variety of blades to create your modular propeller. Read the FAQs below to help you decide which blades are right for your application.
Blade Count

Pitch

Pitch is one of the fundamental characteristics of a propeller. Props are usually sized by their diameter and their pitch. A 14 x 17 would describe a 14 inch diameter with a 17 inch pitch.

Pitch is not an angle, it is a distance traveled. The prop acts like a screw being driven into a solid material. As the propeller rotates it moves forward. How far the propeller moves in one revolution is the pitch. The 14 x 17 would move 17 inches forward in one revolution of the propeller.

Spline

Rotation

Not every propeller is designed to turn the same direction when the boat travels forward. There are always two possibilities.

When the propeller is viewed from behind the boat looking forward: left-rotation (counter-clockwise) or right-rotation (clockwise).

B vs. XB Blades

Propeller Diameter

Diameter is one of the fundamental characteristics of a propeller. Props are usually sized by their diameter and their pitch. A 14 x 17 would describe a 14 inch diameter with a 17 inch pitch.

When choosing a propeller matching propeller diameter is less important than matching the propeller pitch as compared to your old prop.
