Prop Finder
Finding the right prop for your boat is based on the individual boat/engine combination, as well as how the boat is being used. Whether you want to upgrade the stock prop, or just need to replace a damaged prop, our Prop Finder guide will help you determine the perfect prop for your Year, Make, and Model boat.
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 1 1/8" Keyed
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.
Keyed: Measure the circumference of the prop shaft. Do the measurement in the middle of the prop shaft as it tapers as it gets closer to the propeller. Then use this formula to find the diameter. (diameter = circumference / 3.14)
