Howdy my 57 mercury m-100 has a 10.5" clutch and I am trying to find a replacement for it but all I can find is a 10" or an 11". Would these by any chance work on my flywheel? Or would I have to get another flywheel to fix my clutch? It has chatter.

I can't remember the size of my clutch but I got mine from NAPA. I have a 223 with three speed in a '60. If you can get a decent guy at the counter, they should be able to come up with what you need. Or, by all means contact one of the folks that NumberDummy provided.

 

the 6 cylinders had 10 inch or an 11, the 11 was optional equipment the factory one for the 8 cylinders in the 100's and 250's was 10.5.
