Anyone in the marine repair industry is aware of the many complications normally involved with replacing a worn strut bearing. It usually goes something like this:  First you remove the prop, then loosen the flange on the gear (transmission), of which the fasteners are usually rusted or corroded. Next you remove the propeller shaft or the strut.  If the shaft is in line with the rudder, then it too requires removal.  This means disconnecting the steering. All said, this takes many hours of labor, a lot of time involved, and not always free of damage.

With Strut-Pro® this process goes a whole lot smoother since there is no removal of the propeller shaft, strut or rudder.  There is no cutting, beating or destruction of any kind.  Strut fasteners and bedding do not require repair because there is no pressure applied to any area other than the strut. All done in an hour or less.

Now, how does that sound?


Collets are what push out the old bearing.  Strut Pro collets are precision laser cut, then hydraulically formed in permanent dies.  They are made from high tensile Grade 80, nearly three times stronger than stainless steel, then ceramic tumbled and zinc plated.
