One of the issues that keeps coming up here is the cutless/cutlass bearing spec. (Incidentally, the industry-preferred spelling is "cutless" but both spellings are used.) Gerard Warner reported he used a

Johnson Duramax ACID Brass cutless bearing
Shaft Size: 7/8 inch
Outside Diameter: 1-1/4 inch
Length: 3-1/2 inch

but that immediately raises the question, is that the spec for other Marks? C&C tended to stick with its hardware through many years and models (my mast is almost identical to a Mk Is mast, other than in shroud arrangement, despite the many differences in the hull and deck). I expect Gerard's spec will work for all Marks but it would be nice to know for sure.

Later - visited club and measured several boats' p-brackets and bearings. These specs turn out to be identical with the specs (measured externally with a caliper gauge) for a Mk I, a Mk IV and a mid-run C&C 30; clearly, when C&C found something that worked they stuck with it. I think we can be confident of this item.
