Our cupped and cambered blades provide optimal grip for powerful acceleration, higher top speed, better bow lift, and overall peak efficiency. Precision balanced for smooth and vibration free performance. High gloss powder coat finish minimizing drag for peak handling and acceleration while providing long lasting protection for our aluminium propellers. The curved exhaust flare helps reduce ventilation or blow out while cornering by preventing exhaust gases from infiltrating into the propeller.
