My boat is not a Nitro or Tracker (Starcraft Fishmaster 196) but I do have a 200 Optimax and it was the thread about the Guardian "Limp mode" issue that caught my attention and caused me to join. Yes, Google can be your friend, but you also have to sift through a lot of garbage on Google. For example I was having a issue with the oiling system and the advice was to shut off the oiling system and premix the oil into the gas. Well, that would be a disaster since the oiling system also supplies the air compressor and crankshaft....
