Ideally you want rigid surfaces for alignment, so a rubber spacer could make things a bit too inaccurate. So some people make a hardwood/metal disc to use instead of the soft spacer to use for the alignment.

If you can't/won't do that, I suppose you could slide the shaft forward for the width of the spacer (if its quite narrow), do the alignment, and then slide the shaft back a little to re-fit the spacer. That would obviously lose you some alignment accuracy in the process.

How accurate you want to be depends on your situation/vibration.

Speaking for myself, I'm no longer aiming for 0.003", because when I measure a month later, it will have moved away from that a bit. So after a month it seems I end up with the same result had I aligned only to, say, 0.01".
But that's my choice on my boat and you may benefit from much tighter alignment tolerances.

Re: How To Remove Coupler?

Thanks for the feedback. We may have the shaft shortened to compensate for the DriveSaver. We can then have the alignment done without having the DriveSaver in place. I am still waiting for the marina to remove my cutlass bearing so I can slide the prop shaft past the rudder.

You should definitely do the alignment in the water.
