How to use this chart to find the right prop for your engine

1. Find your engine size along the bottom axis.
   
   
2. Follow the line up to where it intersects with the shaded area.
   
   
3. Follow each point within the shaded area to its corresponding prop size on the left axis. This will be your approximate prop range.
   
   

Note: 4-cycle engines are typically higher torque engines and should use the larger props indicated in the range.

Recommended prop ranges will vary depending on your particular engine and airplane. This chart represents average prop usage and should used only as a general guideline. Always refer to the manufacturer's instructions included with your engine.
