[HandsFree]

So, I have a leak of Hydraulic fluid coming from the reservoir cap for steering.  My mechanic says that he cannot put new threads in the aluminum and that the only fix is to replace the entire helm portion of the steering system (for $750 for parts alone).  Have any of you had this problem and if so what did you do to repair it.  Who was the manufacturer of this system for the 1997 3100 open? I am hoping that there is some kind of repair part or kit without replacing the whole thing.  Any thoughts or ideas are greatly appreciated.

Thanks
Dennis
