Replacing idle jets on 50hp, jets in carb. now are, top is #29, Bottom is #33. I understand that this is for high altitude. I don't live in high altitude. But when I check two different parts dealers one tells me to use 31 in top and 35 in bottom. Another tells me to use 33 in top and 35 in bottom. which one is right? Or does it make any difference so long as the idle adjustment screw is set right? Thanks for any help.

Go to shop.evinrude.com and look up your motor in the parts diagrams and see what they show.
