Well, you just do how-to videos.  That’s what you do. So, I am anticipating you 
will do one on this, and looking forward to this!

You are kind of filling Wally’s shoes on the documentation side.

 

I just watched the video, 

https://www.youtube.com/watch?time_continue=9 
<https://www.youtube.com/watch?time_continue=9&v=6xx8qz1Fgk0&feature=emb_logo> 
&v=6xx8qz1Fgk0&feature=emb_logo

and they had tons of space on that.  

 

If I am understanding you right, couldn’t you just poke the bolts through from 
the back to the tranny, so you don’t have the length of the bolts to contend 
with?

Bill, 

 

I can do a video but would like to know what it should focus on... My situation 
and questions, of my ultimate solution?

That’s a lot to unpack. 

I am having trouble visualizing all this, but I am very interested, especially 
in the Last Drop seal, I hope you do one of your famous videos.

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?

 

 

Thanks,
