Re: Broken out of the box
maybe a paypal charge back? the only thing is that it's out of his warranty period and more importantly you ran it, i know it was only like 100 feet but who's to say you didnt cause the damage (not saying you did but thats possibly how BGF will explain it to paypal and paypal may agree).
give it a try, you do have a reason to be upset so i don't think having paypal investigate will effect your account. you'll have to ship the whole motor back to bgf, but he'd lose the sale.
