It's not the same. The Merc part number in that kit is 27-53354, the one you need is 27-96429... And the earlier one does not supersede to the later...

MERCRUISER - (140 H.P. (1985) Serial No: 0A339876 Model No: 01409005 Parts Catalog No: 90-41261. http://www.mercruiserparts.com/selec...?doc_nbr=41261

Outdrive serial number 0A338939
Are you sure that's the correct serial number for the stern drive? It's coming up as an MERCRUISER 120 H.P engine. Either way being an 1985, this parts catalog will work for your stern drive for part number look up. http://www.mercruiserparts.com/selectSerailRange.asp?doc_nbr=R/MR/ALPHA+ONE+(Sterndrive)+1983-1990
