Frank,
I am a nobody to you, but i would like to weigh in. I wouldnt wait one second to call the person, text the person, and emial the person. Confront them, let them know exactly what you know, get a copy and send a copy via email to the customer of the sales reciept. I would let them know they bought the wrong poop, it will blow motor up, and you will void out thier warranty as you have the knowledge of what they did.
Give the customer the option to make it right, if they dont save everything and wash your hands of them.
