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.
Design Features of Ballistic Propellers Ballistic propellers produced by Michigan Wheel Propellers are designed for high performance in all categories. Key features of Ballistic props include the use of stainless steel in all major lines: the 3-blade, the 3-blade XL, and the 4-blade XL. Tapered Edges All Michigan Wheel Ballistic props feature leading edges that are tapered. This not only helps to cut down on drag, but also serves to help the blade design have the ideal amount of strength as opposed to thickness. Overly thick blades, of course, can cause weight issues that make the motor less efficient. Blades that are too thin are also a disadvantage due to the problem of warping under stress. Michigan Wheel has used advanced manufacturing techniques to create a blade geometry with optimal thickness across the entire volume occupied by the blade. Luster Finish Ballistic props by Michigan Wheel also feature a mirror finish that is polished to a high shine. This adds aesthetic appeal to the propeller to be sure, but it also has a practical advantage. A quality finish lends itself to improved resistance to the corrosive forces of fresh water and, in particular, sea water. Other Specifications Ballistic propellers are available with pitch measurements that range from 13″to 27″. In addition, all blades feature the “Power Tip” system, which improves efficiency by carefully aligning blade cup and tip contours so that an optimal design profile is achieved. This feature serves to reduce the loss in power that can result from cavitation.
