I just made an offer on a 1993 23' Grady Gulfstream w/'93 Yamaha 250 and it was accepted! This is my first boat!! The broker is willing to go on the sea trial with me and "survey" the boat. He says he can do pretty much everything the surveyer will do except test the hull for water seepage. Should I trust the guy who stands to make a commission on the sale? Will a surveyer do substantially more than test all the systems? I am planning to use a mechanic to look at the engine. Is a mechanic from the marina who is brokering the boat a wise choice? They're right there and are dealers in the engine that's on the boat. The broker says the boat has been serviced at the marina since it was new. Are boat brokers generally truthful!!?? (As opposed to used car salesman!) Whew!! First boats are rough!!
