Turning Point MasterGuard Hub Kit 505 — 11500500
Description
Description
Turning Point MasterGuard installation kit 505, manufacturer part number 11500500, adapts a compatible propeller housing to the specified engine/drive shaft. This is the hub/installation kit; a propeller housing is not included.
Application and exclusions
15-spline Nissan/Tohatsu listed 60C/70C, 70 (2002–2009), MFS75–140 (2021+), non-BFT 90–140 and 115 TLDI (2014+). Yamaha 4.25-inch 2-stroke 115–130 and 4-stroke 75/90/100 (2017+), 115; also listed larger Yamaha 150–250, V6 F300 (2009+) and sterndrives 3.0–7.4 L. Select the correct duty rating for stainless props; Yamaha Express Mach3 OS applications call for 805FT instead.
Applications above are summarized from the manufacturer’s 2025 selection chart. Use the current Prop Wizard and exact engine model/year, gearcase and spline count to confirm before ordering; an engine brand or horsepower match alone is insufficient.

Construction and warranty
MasterGuard uses a one-piece hub design with a polymer cushion and corrosion-resistant metal splines. Turning Point advertises a lifetime hub warranty; the 2025 chart limits the 500- and 700-series lifetime warranty to non-commercial use. Coverage is subject to the manufacturer’s terms and does not provide a lifetime warranty on a separately purchased propeller.
Installation checklist
- Confirm engine model, year, gearcase and spline count, then match the hub and prop housing in the manufacturer’s guide.
- Use the hardware specified for this kit and your engine. Included components and reused OEM hardware are application-specific; follow the kit’s instructions.
- Follow the engine manual for torque and locking hardware. Check propeller and trim-tab clearance before operation.
- After a prop strike, inspect the propeller, hub and drive before reuse; replace damaged parts.
