[QUOTE="hankthecrank, post: 408435, member: 18463"] I have a 89 evinrude tracker that is identical, 20 hp that is now a 30hp. Ive seen that carb number before and I think your'e right, it doesn't trace well. I don't think i ever actually found that number. There are several carb numbers that were discontinued , superseded whatever, but they all are basically the same. 20 to 30 usually changes a main jet, 35 has a bigger throat in carb , bigger jet and a manifold with more volume. Search around this forum for evinrude / johnson hp changes. A lot of good info there along with build threads. Hank [/QUOTE]
