Rotation & Diameter
Rotation: Like bore, rotation is specific to the power train of the boat; if your boat needs a left-hand rotation propeller, you must use a left-hand rotation propeller.
Diameter: In general, a larger diameter means more surface area, which means better transmission of power from the engine to the water. Typically the diameter is limited by clearance around the prop, which is very important to check.

Cup & Pitch
Cup: is the curvature of the blade at its edge, primarily translates to the amount of load the prop will put on the motor.
Pitch: is the distance the prop would travel after making one full revolution. A lower numerical pitch number means higher engine RPMs relative to boat speed, which translates to better performance for slower speed activities.

Shaft Size Spline
The bore of the propeller is specific to the prop shaft that is on your boat. Shaft size is not interchangeable, you must use the correct size prop for your boat’s shaft or the prop won’t fit.
