Hi, yes you will need to get new high speed jets. They are in the bottom of each carb, you will need 4. You will order them from any Evinrude dealer. Let me see if I have that chart here or I may have to get it from the shop tomorrow morning.Probably 52C for the high speed and 36 - 38 for the low speed jets.But before ordering let me double check.
