Survey is something that should always be done as many have mentioned. As far as hours, the buyer should have asked for a computer print out too. Many shady characters in the marine industry. However, I believe David Woods at Pier 57 in Pickwick TN, Scott Shogren in Chicago, Phil @ Lip Ship are reputable and honest. I am sure there are many others out there too. I believe performance boat brokerage at LOTO is a straight shop, haven't heard any bad news about them either. Just have to talk with them and ask around. Sorry to hear about your buddy's experience.
