The Piranha modular design allows for blades to be replaced due to damage or to be re-pitched for performance. The key to the patented Piranha boat propeller is the hub. The center hub is made from a high-strength aluminum core, over molded with our specially-formulated composite material. The propellers are made from Verton, a composite non-corroding material. Verton is a compound based on a polypropylene resin containing 50% long glass fibre - it is chemically coupled, heat stabilised and uv stabilised. The manufacturing process is so precise that the bladed shape and pitch distribution is superior to stainless steel and aluminium blades.
The Piranha blades are designed to absorb the shock of a propeller strike, which virtually eliminates lower unit damage. The Piranha hub is so strong that it is guaranteed for life, “you damage it, we will replace it.” The Piranha design also eliminates spun propeller hubs.
The replaceable blades are manufactured from a specially formulated high-strength aerospace composite material. The manufacturing process is so precise, that the blade shape and pitch distribution is superior to Stainless Steel and Aluminum. Blade balance is no longer a problem as the Piranha Propeller blades are balanced to 2 times the industry standard. The precise balancing reduces lower unit damage caused by vibration.
Repairing or replacing lower units is expensive. A propeller is a critical component to the performance of a boat. Damaged propellers will not only degrade performance, but can cause excessive wear on the lower unit. Spare Piranha blades are easily stored, and replacement of a damaged blade only takes a few minutes. With the replacement blades on hand, it is simple to restore a damaged propeller to factory new specifications.
Shopping for a quality outboard propeller can be extremely challenging. Propeller designs come in a variety of sizes and configurations. The support team at Piranha is available to assist in making the optimum propeller choice for your outboard or sterndrive.
