I personally advertised an engine on RIB.net (
http://rib.net/forum/showthread.php?t=26230) for a customer who I had previously sold the engine to on the back of a rib. The advert says it all.
A nice chap who is a Master Mariner Engineer in the Marine Trade phoned regarding the engine, Ed from Olmec had seen the advert and put him on to me. He asked very few questions, didn't want to see it, paid for it by transfer and sent a courier to pick it up from my house. I made £150 on the transaction to cover my time.
A few months later I get a phone call to say the prop shaft is a few thou out and its thrown a con rod out the side of the crank case. The chap sounds very reasonable and honest, but then again I know the engine was 100% fine and running when it left on the courier. If the chap didn't sound so honest I would think the prop had been in contact with the hard stuff.
As it was a brokerage sale and the customer chose not to view or survey the engine, legally I don't have to do anything.
But what should I do?
