Propeller Cup Explained at Lorena Wright blog

Propeller Cup Explained. Cupping also reduces the tendency to cavitate, which can damage the blades. The design on many propellers includes a cup on the blade's trailing edge. When a boat is cupped, the propeller blades are slightly bent inward. so, what does cupping a boat propeller do? This will translate into a subtle change. The face of a cupped prop blade is concaved. If the boat is operated at certain speeds where propeller efficiency is improved due to cup, then there should be an increase in fuel efficiency. This cupping or curved lip on the blade. Typically not an issue for most of our customers, propeller cup plays a fairly limited role in propellers for watersports boats. Cup, or the curvature of the blade at its edge, primarily translates to the amount of load the prop will put on the motor. For example, if a fishing boat spends most of its time trolling, at low speeds and engine rpm, the benefits of propeller cup will probably not be noticed. propeller cup helps with propeller efficiency. More cup effectively adds more pitch to a given prop, increasing speed if adequate power is available to reach maximum rpm. Propeller cup is simply the deformation of a propeller™s trailing edge toward the pressure face. Cup is a curl formed or cast into the trailing edge of a propeller blade.

Cup, or the curvature of the blade at its edge, primarily translates to the amount of load the prop will put on the motor. cupping or adding a cup is a pretty simple geometric change of the trailing edge of the propeller blades.
