Ok, I'll admit it. I usually grind down a 1" collar zinc for our shaft about once every 2 years, as needed. We only have a clearance of around 1/2" between the prop and the cutlass bearing on our old Tartan 27.
I looked into the 'drive savers' but since zincs are cheaper I keep grinding them down with: a grinding wheel, a 4-1/2" grinder and breathe zinc dust now and then.
Not much fun and there has to be a better way.

What is the width of clear shaft you are dealing with?

I have a small metal lathe, if some one needs to they can send me a few zincs and tell me how small they need them. i will turn them down to what ever size they need.

just pay shipping both ways.

You could also just grind them down a bit with a belt sander.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Depends on whether it has four bolts holding it together or just two... if it has four, then that would work, if just two, probably not going be worth doing.

1" shaft zincs do not have 4 screws, regardless of brand, so this is a moot point.

I have used a hacksaw to shave zincs and more recently, a portable band saw. That makes quick work of the job.
