[C320-list] Shaft Replacement

[Jeff Hare]

Hi Paul,

I ordered the SS prop shafts online from:

Deep Blue Yacht Supply.  www.deepblueyachtsupply.com

The shafts I ordered were;

Length:   55"
Diameter:  1"
Single Taper
Price:  219.85 + shipping ($20?)
Part # SHAFT A-19  Aqualoy 19, which is nitrogen strengthened 304 SS.   (SAE J755 taper spec)

They also have an Aqualoy 22 which may be an option if you need even more corrosion resistance.  They have info on the diffs.  These are more money but probably not necessary.

With this shaft you will need to drill out 2 set screw dimples for the locking set bolts in the coupling flange once you get the shaft installed where you want it.  These keep the shaft from sliding out of the coupling.   

I don't have the supplier handy but purchase a new cutlass bearing, and shaft log hose at the same time.  The spec for the shaft log hose (that holds the stuffing box) is available in the owners manual.  It should NOT have wire reinforcing and I ordered from my local service yard for a couple bucks.

PS: you have to be a C320 member to borrow the tools from the association.

Thank you Jeff.  I would be interested in the place that you got the  
shaft.  The marina wants a lot of $$$ to do the replacement.  I think  
it is possible that the marina created the problem when they hauled  
the boat.  I have a 1/4" bend starting just after the cutless.  Don't  
you think I would have a lot of vibration in the boat if it was there  
earlier as a result from hitting something?
