[C320-list] Keel Bolts

[Chris Burti]

There is a different schedule for torquing dry threads and dressed threads- higher torque for dry.  This might be the reason for multiple numbers - different answers for different questions.

You may not get an accurate torque on the keel nuts unless you are dealing with clean threads and a nut that turns freely against a clean surface.  Be sure it isn't frozen by loosening the target nut first and inspecting the threads and giving the threads a shot of drylube or Moly-kote or other anti-galling grease before going for the actual torque value.  Then move on to the next.  You don't want to risk galling the threads, so some lubrication might be important.  BUT I DON'T KNOW for sure.
