MasterTorq® 805FT SDH Hub Kit — Sound Dampening Hybrid Design
The MasterTorq 805FT SDH is a next-generation hybrid hub kit that combines the shift shock and vibration dampening of a traditional pressed-in hub with the ease of installation, replaceability, and long-term reliability of a modern drop-in design. Engineered for outboards and sterndrives 40hp and above, it’s a single all-in-one hub that solves the trade-offs that have defined hub design for decades.
Best Use Case
The 805FT SDH is the right choice for boaters running 40hp+ outboards or sterndrives who want meaningful vibration and shift shock dampening without the drawbacks of a traditional pressed-in hub. The “T” designation indicates a specific fitment variant — it differs from the 805F in engine application. It’s particularly well-suited to higher-horsepower applications where engine vibration and shift harshness are noticeable — including performance boats, larger pontoons, and sterndrives where smooth operation and lower unit protection both matter. Confirm your engine make, model, and year against the application chart to verify the 805FT is the correct model for your setup.
How It Works
Most hub designs force a trade-off: traditional pressed-in hubs offer good vibration dampening but are difficult to replace and can lock solid under impact, increasing the risk of lower unit damage. Newer drop-in hubs are easy to replace but often sacrifice dampening. The MasterTorq SDH bridges both worlds — its Hub Isolation Technology and rubber dampening material absorb shift shock and vibration under normal use, while still being engineered to break away cleanly under impact to protect your lower unit.
Key Features
- Hybrid Hub Technology — Combines the vibration and shift shock dampening of a pressed-in hub with the ease of use and replaceability of a drop-in design.
- Hub Isolation Technology — Additional dampening layer reduces engine vibration transmitted through the drivetrain.
- Rubber Shift Shock Dampening — Absorbs the jarring associated with gear engagement, reducing stress on the engine and drive.
- Breakaway Lower Unit Protection — Engineered to release cleanly under impact — unlike competitive designs that can lock solid and transfer full impact force to the lower unit.
- DIY Replaceable — Designed to be replaced by hand without special tools.
- Reliable Under Normal Use — Will not let loose or spin under standard operating conditions.
- Broad Engine Compatibility — Adaptable to many outboard and sterndrive brands.

Parts Desk Insights
Confirm compatibility before ordering. The MasterTorq SDH series includes multiple models — the 800F, 801F, 805F, and 805FT differ in fitment by engine make and model. The “T” suffix on the 805FT indicates a specific fitment variant distinct from the 805F. Refer to the application chart for your specific hub part number before purchasing.
