Prop Pitch & RPM's
For safety, and efficient performance, it is critical that your engine operates within the RPM range recommended by the manufacturer.
A change in the prop pitch will increase or decrease the engine RPM's and can be used to bring them into the recommended range. A 2" pitch increase (for example, from 21" to 23") will result in approximately a 300-400 RPM decrease and vice versa.
The correct prop allows the engine's RPM to run within the top end of the manufacturers recommendation.
