Turning Point MasterGuard® 700 Series Hub Kit — High-Horsepower Installation Kit
The Turning Point MasterGuard® 700 Series Hub Kit is engineered for high-output outboard and sterndrive applications over 200 horsepower. Built around premium corrosion-resistant brass splines, this kit is designed to handle the torque demands of powerful engines while protecting your propeller investment from costly damage.
The 700 Series features a doubled internal bearing surface compared to standard hub kits, substantially increasing strength and shock absorption — critical for high-horsepower installations where prop strikes or sudden load changes can destroy lesser hubs.
Best Use Case
Purpose-built for high-performance outboards and sterndrives over 200 HP running a 4.75" gearcase. This is the right kit when you're running a Turning Point stainless steel propeller on a high-output engine and need a hub that can handle the stress. It's also a direct upgrade path for boaters who want to improve shock absorption on an existing installation. Consult the Turning Point application chart to confirm fitment for your engine before ordering.

- Turning Point Express Mach3 — 3-blade stainless steel

Parts Desk Insights
The 700 Series is the kit to reach for when a standard hub won't cut it — particularly on twin-engine setups or high-performance single-engine boats where torque loads are extreme. The doubled bearing surface is a meaningful upgrade over entry-level kits and we see far fewer hub failures on high-HP installs when this series is used. Always verify your engine's gearcase diameter (4.75") and check the Turning Point application chart for your specific motor before ordering. If you're unsure whether this kit fits your engine and prop combination, reach out — getting the hub right the first time saves a lot of headaches on the water.
