Have you seen this engine??

[Hellother]

did he tell you to send it as a gift? You could actually stick it to him if he told you to do it. Then you would just have to argue he had the intention of scamming you. btw a deposit is a binding contract. the agreement was for you to give x in exchange for y, if he receives x but does not give y, then he breaches the contract and your entitled to you money. that's pretty much how it goes. doesn't really matter if a cracked out seagull beat him to death and took the motor from him. he didn't deliver your entitled to your contribution.

edit: gift and regular paypal is just so paypal can get your money back for you. but when it comes to court, emails and texts showing outline of said agreement. money transfer, lack of product. he's liable. the contract is the contract.
