Turning Point Propellers 91103004 MasterGuard Propeller Hub Kit

The Turning Point Propellers 91103004 is a MasterGuard Series propeller hub installation kit designed to mount compatible Turning Point propeller housings to outboard and sterndrive engines. A hub kit is required to install any Turning Point propeller, as propeller housings are sold separately.

Turning Point's MasterGuard hub system features a patented one-piece design constructed with durable marine bronze splines overmolded with glass-filled nylon. This eliminates the failures commonly associated with traditional multi-part "sleeve and spline" designs and pressed-in rubber hub systems, delivering long-lasting, reliable performance.

Key Features:

• Patented one-piece hub design with marine bronze splines and glass-filled nylon overmold
• Absorbs shift shock and reduces harmful vibration to protect the lower unit and drivetrain
• Hub is reusable in most cases following a propeller strike, reducing replacement costs
• Engineered to withstand normal operational use without risk of spinning or hub failure
• Compatible with Turning Point Express Mach3, Mach3 OS, Mach4, and Hustler propeller housings
• Also compatible with Solas Rubex, Michigan Wheel XHS, and Mercury Flo-Torq propeller housings
• Lifetime warranty — the only lifetime-warranted hub kit in the marine industry

The MasterGuard system allows boaters to keep their hub when replacing a damaged propeller housing, saving up to 33% on replacement costs. This kit includes the hub and all necessary hardware for installation.
