Hey guys , I've got a 90 hp Honda that II recently purchased used . I put it on my Carolina skiff and it busted right off . I noticed that it was idling rough and kind of slow to rev up , just not very responsive . So I tore the carbs down and found why I was able to get the motor so cheap . The jets are all broke off and some of the other replaceable / rebuildable parts are ceased beond believe and almost everything brass is stripped on all four carbs . found the whole carb assembly on ebay for couple hundred dollars but its for a 115. My question is are the carbs interchangeable from 90hp to 115hp . They appear to be the same from what I can see in the pics .Also thought they might just have bigger jets and maybe I'd just be converting to a 115 . I don't know . I would really appreciate anyone who has knowledge on the subject . Don't really want to spend the 1100$ on a new set of carbs if I don't have to .

I think if the fit it would be to rich. I have a BF75A and all I need to do to make it a 90 is use the carbs and intake manifold off a 90 as all the other parts are the same.

So if it takes it from a 75 to a 90 I would guess 115 to 90 it would be to rich
