what does the pitch of a propeller mean
Pitch is defined as the distance a propeller would move in one revolution if it were moving through a soft solid, like a screw through wood.. For example, a 21-pitch propeller would move forward 21 inches in one revolution.Think of a propeller as you would a car's axle ratio. The lower the ratio, the more pulling power from a standstill. The same is true with a prop. The lower the pitch, the better your hole-shot.f you don't know, diameter and pitch usually are stamped somewhere on the prop. Also know the engine's rpm at wide-open throttle when your boat is running with a typical load and trimmed for best speed. Perhaps what's most important is your performance goals.
