Piranha Propellers offers a unique advantage to boaters by combining durability, versatility and affordability. The company offers an extensive product line for outboards ranging from 9.9 to 280 hp. Constructed from an aluminum core and a composite housing, the center hub is virtually indestructible and provides drivetrain protection when hitting immoveable objects. Piranha Props' patented design provides the ability to re-pitch or replace damaged blades while still on the water. Additionally, the cost of replacement blades saves consumers as much as 70 percent over the cost of standard repairs. All products include a 30-day money-back guarantee.
