Additional Information
Features
Turning Point's Hub Kit Systems are engineered to withstand typical wear and tear over time without risk of spinning or failure under normal operational use. Hub kits feature a unique patented one-piece hub with glass-filled nylon over brass splines to eliminate failures commonly seen in multi-part "sleeve and spline" designs and pressed-in rubber hub systems. Glass-reinforced high-tech polymer construction increases flexibility, eliminating potential stress fractures. High flow-through barrel exhaust system maximizes exhaust flow to increase horsepower and top end speed. Clear step-by-step instructions make installation easy.
Turning Point's 500 series hub kits (for 4.25" and 4.75" gearcases) will upgrade and replace Mercury Flo-Torq II, Michigan Wheel XHS, and Solas Rubex hub kit systems.
Propeller Housings are sold separately.
MasterGuard 507 Hub Kit Only - 15 tooth spline.
MasterGuard 507 Applications:
Honda/Johnson/Suzuki
• 60 - 300 HP engines with 4.25", 4.75" gearcase
