[QUOTE="m casey stock, post: 311867, member: 8635"] Okay, update...the carbs and intakes on the 30HP and 35HP are the same, so no need in me spending that money unless I want to put them on my 1988 Johnson 25 (which I may do for the better idle qualities that has been previously mentioned) But the aftermarket reed/leaf valves should add 5HP. This leaves me wondering what the actual difference is between the late 80's early 90's 30HP and 35HP motors. I see that the factory reeds/leaf valve are also the same on them. So where did Johnson get the 5HP gain? Is is something even more simple than the carb. swap? I'd love to hear from someone that has the answer to that. Of course, if I find the answer, all of you guys will have it too. [/QUOTE]
