I am trying to find out if I have the original block on my boat and get the accurate year of build. 2002 Starcraft, Mercruiser 3.0 M035849 is s/n on the tag above the starter. Tried poking around a few parts sites but this number does not show up as found. Sterndrive S/N is OL972683 and transom is OM219934
many thanks
