    Usually "big bore" carbs on an X-flow are considered 1 3/8". I probably have a set of 1 5/16" and/or 1 3/8" but I would need to go through them. If I don't have them, one of us x-flow loving idiots should have something for you lol. What size motor are they for?

    Ya, you would have to mod the crap outta a 150 to make 1 3/8" carbs work.......even at that, it still prob wouldn't make sense, especially on a lake boat. I will see if I have a set this week.

    I have a set of factory 1 3/8 off a 1988 GT/XP150 (that year some of the 150HP S motors came with big bore carbs). Been gone thru and ready to run. $175 shipped to lower 48
