You are sure the skeg and gearcase are original matched parts?  Sure sounds like a possible mis-match to me. everything in there is located by the upper gearcase, except the shift fork pivot pin, which is located by the skeg.  I’d be using an inside mike to measure the roundness of the bore, bolted together without the prop shaft parts.
