My "engine kill" ( or engine shutdown cable) has seized up and is no longer functioning. Have tried to spray WD40 hoping it will penetrate the metal sheave and free up the internal wire. No luck so far. So, it looks like the cable will have to be replaced. Has anyone actually replaced theirs? What would you call this type of control cable when ordering it? I am still down in the Rio Dulce and will try to find an replacement here,although I expect I will have to order it from the States. If you have replaced this cable, I would appreciate any feedback or suggestions you have
