You did awesome. Since the tag says 4395 and the unit has 4400 on the clock, that means the engine only has 5 hours on it. Run it with break in oil for the first 100 hours to make sure you have a good break in period. If you have time will you report back as to what the tag under the hertz gauge says so everyone will know.the numbers on the tag under the hertz gauge is 4395 I Paid for it $1995
