I recently bought an 89 f-23 center console,and the boat was built in late summer of 88.I need to recheck the hull # but I think it was july or aug.1988 build date.Actually still have orig MSO papers.Would that be the old donzi company?I thought the sell to omc was later than that.It is built pretty tough,and no stress cracks anywhere.The decks and interior gel compounded and waxed up great.Hull sides are getting paint,original yellow.
