Flo-Torq Hub Kits

Mercury Quicksilver Flo-Torq® Hub Kits

The Mercury/Quicksilver Flo-Torq interchangeable hub system provides the ultimate in drive protection – the Delrin sleeve sacrifices itself to protect key drive components in the event of contact with an underwater obstruction, while still giving you the ability to idle home safely.

The sleeve can be easily replaced, eliminating a costly trip to the repair shop. In addition hub kits are available to allow the easy use and improved performance of genuine Mercury propellers on most outboards and sterndrives!

In 2021 Mercury Marine discontinued including hub kits with most stainless steel propeller shipments so you customers could have the freedom of choosing the ideal hub kit for their application. Check out our hub kit selection chart to find which Flo-Torq® adapter kit works with your engine. Q and K in part numbers can be interchanged; the only difference is packaging. Individual hub kit parts including adaptors, sleeves, etc., are at the end of this page.
