Another place to get the shaft you are looking for is Bakes Marine. I just finished this major process with their great assistance. Shipping will not be cheap from anyone. SKIDIM didn't have the one I needed available for a couple of weeks in my case. They are always my first choice though.
And, you may want to order new cutlass bearings as they are not expensive and may need to be changed out (mine did), AND perhaps install a dripless shaftseal which are also available there. They have the OJ system, but I went with the PSS system. TOTALLY WORTH IT.
