Crafted from top-quality 15-5ph stainless steel with a high-luster mirror finish, Michigan Wheel's Ballistic Props not only reliably withstand nicking and bending, but they also offer exceptional corrosion resistance even in the harshest marine environments. They're designed with unique cambered blade sections to ensure better bow lift, greater speeds and smoother, more stable handling. The unique power tip blade also offers enhanced out-of-the-hole acceleration and virtually eliminates ventilation during tight turns. And in most cases, these innovative props actually reduce RPMs so the engine works more efficiently. A special shock-absorbing hub prevents damage to gears and shaft caused by shifting and impacts with under-water hazards. Ballistic XL props are specially engineered to give boats with higher-horsepower motors (over 80hp) extra lift for better top-end speeds. They reduce the hull drag, cavitation, steering torque and vibration generally produced at higher speeds. All Ballistic Propellers use standard OEM hub geometry for easier installation, repair or replacement. Limited lifetime warranty. Ballistic propellers have a pressed in hub, so you do not need the XHS Hub Kit with this propeller. Be sure to try out our Propeller Guide to find the right propeller for your engine.
