The Piranha boat prop hub is so strong that it is guaranteed for life, “you damage it, Piranha Propellers will replace it.” The Piranha Propellers design also eliminates spun boat propeller hubs.
Lifetime Hub Warranty
The heart of a Piranha Propeller is the aluminum cored center hub. This part features a lifetime guarantee. If you damage it for any reason, Piranha Propellers will replace it for you (shipping charges not included). Propeller blades on the other hand are not warranteed except for manufacturing defects. They are designed to break under significant impact to protect your gearcase.
