Hello, I recently bought a GTX 155 2018, 44 working hours. I noticed it has a black outline inside the hull, does that indicate the carbon seal is worn out, do I have to worry? How many more working hours can it last? I am attaching a picture. Also please information if this model had a problem with the IBR or the IBR engine?
