My other boat has 22 x 22 4blade nibral Michigan Wheel props, 1 3/8" shaft.

I have been looking for a cheap set of used get-home props, but they all seem to be 1.5 or larger.

Does somebody make bushing to reduce a larger-bore prop? Where can I get a couple?

1 3/8" is a weird size ? usually jumps from 1 1/4-1 1/5 ?? but I have never seen a bushing to do that..would not use one if they made it.....don't think you would ever get to seat right..??

Yup, it is most definitely 1 3/8" shaft, with a taper at the prop mating surface. Measured multiple times. I then went to a Carver related website and they verified it for me, because like you it sure seemed like an odd size.

There are bushings made to reduce bore size. Anchor Bushings is the most well known manufacturer.

Hey PhilM- THANK YOU! Only 27 bucks each!

I just bought a nibral michigan 22 x 22 x 1.5 on ebay for a hundred bucks. So I'll have 127 into a spare prop that I could use all the time if needed. What a deal Now looking for the RH side.
