T&T: Shaft Coupling

[Ron Nelson]

I was told by a mechanic that one should place the shaft zincs in such a place
that will allow the shaft to be backed out enough to allow it to be
disconnected from the tranny.  If this isn't done and you need that type of
work done, you will have to add the price of a diver to remove the shaft zinc
to the price of the mechanic waiting for this to be done.  The best place for
the retaining zinc is inside on the shaft as another poster said.

  Many folks place the prop shaft zinc onto the shaft just forward of
  the strut to keep the shaft from exiting the shaft log. Placement of
  the zinc is a little more critical if your shaft has a dripless
  bearing, but, again if the zinc is just a little ways ahead of the
  strut, it cannot come out of the log. Most folks that use this
  "trick" set the zinc so that the shaft can come cleanly out of the
  coupling to keep it from ruining the shaft and coupling (by spinning
  the shaft in the coupling), and still keep it from exitting the shaft
  log or letting the prop hit the rudder.
