What is propeller pitch?
Pitch is the distance that a propeller would move in one revolution if it were moving through a soft solid, like a screw in wood. When a propeller is identified as 13 3/4 x 21, it has a 13 3/4″ (35 cm) diameter with 21″ (53 cm) of pitch. Theoretically, this propeller would move forward 21″ in one revolution.
