Find the Right Propeller for Your Boat

Find the right Piranha Propeller to go with your MerCruiser engine. Your boat’s engine will work with either the HMA3 or MA4 Piranha hub depending on if you prefer a 3-bladed or 4-bladed prop.

In order to use our prop finder, you will need some information about your boat engine starting with the year it was made and the horsepower. For MerCruiser engines, the same hubs will work whether you have 3.0, 4.3, 5.0, or Alpha 1.

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!
