Hi I have a 94 753 Bobcat with a V2203-B Kubota engine. It currently has 2800 hrs. What is the life expectancy of these engines? Am I near the end?? The machine will basically get light use....snow removal in the winter and lanscaping our house when we build in the summer. I might put 150-200 hrs in a yr on it? How many hours is everyone else running?? Thanks!
