Mercury 175 sport jet shaft/gear

Does anybody out there have any clue where a person could find part # 857013t? I have been looking for a couple weeks and am still empty handed. Hoping someone knows of a junk yard or has one laying around. Thanks in advance

its NLA....and, very likely, low volume...so not too many sources at this point...a search engine is likely to be your best bet...
