boat brokers

Just a frustrated post about buying a boat from a “boat broker” dont buy on a persons word. I did and because of that, I will end up spending alot of money to fix a problem that was there and covered up… I know I should have taken it to a respected mechanic to check before buying, but I didnt thus my fault. What ever happened to a mans word?? Point I want to get across is to never buy a used boat without doing your home work and research. I know I will not and for sure never buy or recomend them to anyone except my worse friend.
