Find the Right Propeller for Your Boat

Find the right Piranha Propeller to go with your OMC engine. Your boat’s engine may work with the following Piranha hubs: YB3, HOA3, OA4, OB3, or OB4.

In order to find the correct hub assembly for your new propeller, you will need some information about your boat engine beginning with the year it was made and the horsepower. You may also need to know some model details, such as if it’s a Stringer or Cobra.

Find the correct hub by scanning the table below, using our automated Prop Finder, or giving us a call at (800) 235-7767. We want to make sure you have the correct components for optimum performance for your application!
