Quicksilver 835257Q1 Flo‑Torq II Hub Kit – Propeller Hub Kit for Mercury, Mariner & MerCruiser

The Quicksilver 835257Q1 Flo‑Torq II Hub Kit is an original, modular propeller hub system for numerous Mercury, Mariner, and MerCruiser engines. The Flo‑Torq‑II system was the world's first modular hub system for outboard and sterndrive drives and offers excellent protection for the gearbox, drive shaft, and propeller.

Thanks to the field-serviceable design, the entire propeller does not need to be replaced in the event of damage – the hub kit can simply be replaced. The system dampens shocks during bottom strikes or shifting, thus protecting the entire drivetrain from expensive consequential damage.

This new version of the Flo‑Torq‑II system features a stainless steel bushing (SS) and a revised washer. It can be used without problems instead of the older version with a brass bushing.

The kit is suitable for a very wide range of engines, including powerful outboards as well as MerCruiser Alpha and Bravo One drives (under 400 hp).
