I have been doing some studying up on the different carbs that can be used on a 2002 59ci merc. The carbs between 1991-1997 and 1998-2005 look the same, so can you put a 1995 60hp carb on a 2004 60hp? And I know that the 75hp-90hp and the 100hp-115hp are same physical shape with different size venturis and main jets, but are all the little air holes the same or are there other differences as well?
