Propeller Basics - Pitch
Pitch
 Pitch is defined as the theoretical forward movement of a propeller during one revolution -assuming there is no "slippage" between the propeller blade and the water. For most boats, there is slippage and therefore the distance advanced is less than the design pitch. The amount of slippage varies from boat to boat.

Pitch is the second number listed in the propeller description.
Pitch is the forward movement of the propeller after one revolution assuming there is not slippage.
