I have a 1990 mercury 90 horse 3 cylinder. And I am looking at a set of carbs for it. My carbs had the marking of 3301-9012 on them. I am looking at a set of carbs off of a late 80's 75 horse mariner with the same exact number on them. Will these work alright? I believe I was reading that quite a few different hp motors back then used the same carbs is that correct? Thanks
