One of my drives was eating drive oil, so I had the tech take it apart. Sure enough the yoke seal was leaking. No big deal. Well, since I bought the boat used and have not been through the drives, I thought we should check them out. Found out all the upper gears had pits on them (no wonder that drive had some whine) The clutches also had some scuffs on them. The bottom end looked pristine. My tech thought it was only time before I had serious drive problems if left alone, so I bought a new upper XR and I am back on the water.
Question: What causes pits on the faces of all the gears?
Now I have this old XR upper that I would like to build up to be as bullet proof as possible. I am not that knowledgeable about drives (yet) so help me out. Exactly what would you
do and what parts would you buy to make the strongest Bravo XR upper???
