I have a 2000 model 115 Evinrude and the gear control seems to not have the amount of travel that it used to have, I cannot get enough shift to get both forward and reverse, the cable is good (replaced) the engine shift is OK if moved manually without cable attached, I guess something must be worn/broken in the control box, any clues as to what wears in them?? or is a "kit" available, I have had a quick look and it all SEEMS OK.
