I've asked a few of you personally so if this is a repeat then please
disregard.

I'm in the process of replacing/rebuilding the drive train on my C&C 37+.
In the process I'm replacing the shaft, shaft coupling, shaft seal and
strut bearing.

The old seal was a PSS seal and the old coupling was a standard solid
coupling.  I had had a R&D Marine (PYI) coupling dampener and planned to
reuse.  The new seal is a Last Drop II from Sailor Sam's.  The new coupling
is a split coupling from R&D Marine.  The new seal and coupling have added
length which ultimately leaves only about 1.5 inches of free shaft at most.

So here comes the question.

First:  Any concerns with only having 1.5 inches of free shaft?  I have 3.
- getting the coupling dampener installed requires the couplings to be
separated by not just the thickness of the dampener buy rather by the
thickness of the coupling bolts.
- getting the split coupling on could be complicated
- with the shaft seal bottomed out on the log there is less articulation
available in the seal tube.  The seal uses a delrin bearing to center
itself on the shaft but without room to flex the bearing will just ride
harder on the shaft and can even overheat.

Second:
The seal engages with the shaft log by at least 4 inches.  If I cut the log
shorter, then I could push the seal deeper onto the log and get a bit more
free shaft and room for the seal to articulate.  Can any of you see any
drawbacks or pitfalls to cutting the log short?
