There is no way to match a motor serial number to a Gator.
also, how can i determine the year of manufacture for the gator? is there a place/way i can run the kawasaki serial number and compare it's date of manufacture to the gators? i want to see if the engine has ever been replaced. i do not know the history, but it seems to be running fine at the moment.
Just got a 6x4 gator and it has nearly 4000 hours on it.
