The Nemesis will provide a 16-25% faster acceleration, superior holding with no penalty in top speed vs. a comparable 3 blade aluminum propeller. If engine RPM is appropriate with 3-blade prop, replace with the same pitch Nemesis propeller. The high quality casting and durable high-gloss Phantom Black finish make it easy to maintain & repair.
