The Rubber Hub
Majority of propellers in the past used a pressed in rubber hub to drive the propeller. There were two original
reasons for manufactures to use a rubber hub. First, to adapt different propellers to various different prop shafts.
Second, to protect damage to gears in your drive upon impact to submerged solid objects. The biggest
disadvantage of a rubber hub is the installation. A rubber hub must be professionally installed by a prop shop and
usually costs roughly $75 - $150.

The Hub-Kit
The innovation of the Hub-Kit has changed the propeller industry as we once knew it. Today, with the
ability to change the hub in your propeller with only a prop wrench gives the consumer the ability to
have several different propellers with only one Hub-Kit. Also, for under $20 a spare plastic insert can
accompany you on any outing eliminating the chance of being dead in the water with a spun hub. The
Hub-Kits are equipped with the same drive protection device as the rubber hubs once had and will
decrease the chance of major damage to your dive upon impact.
Ordering
When ordering a Signature Propeller you must also order the correct Hub-Kit. You must find and
select your engine and drive application below to accompany your Signature Propeller, unless you
already have a propeller equipped with a Hub-Kit. The two common kits are the Mercury Flo-Torq II
Hub and Michigan XHS Hub.
