Ballistic Boat Props are crafted from top-quality 15-5ph stainless steel prop 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. In most cases, these innovative stainless boat props actually reduce RPMs so the engine works more efficiently. Michigan Wheel Ballistic props have 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. Ballistic Stainless propellers are backed by Michigan Wheel's limited lifetime warranty. Ballistic props 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.
