Need shaft coupler - any suppliers known?

[W32PAMELA]

Try General Propeller in Brandenton, FL. I got a new shaft and coupler from them last year. They were very helpful.

The face is connected to a Drive Saver, which by its nature is a bit flexible.

Just seems like alot of variability to me, and precision that takes place in a shop, but may not translate to the actual install.

I have people telling me 'this is the best way and we need to remove the shafts' and others telling me that 30 mm is 30 mm, it's a split coupling anyways, and connected to a Drive Saver, so don't worry about mating them up.

30mm is not an unusual shaft size in Europe (it's what I have! actually quite common) ... perhaps you should look to source from a EU supplier.

I purchased a replacement shaft and coupler from Deep Blue Yacht Supply late last year. Give them a call and they may be able to help. I believe you can have up to 10 mils (0.010 inch) of difference in alignment when using a flexible coupling or drive saver. If the new coupling has been manufactured properly it should already be true to the shaft bore.

Fine, do whatever you are comfortable doing. I wouldn't be comfortable selling your solution to one of my customers, but that's just me being cautious of creating possible callbacks.
