Wow...sounds like a great shop If you were able to pick up your boat I would try to work out some type of agreement with them and come to terms on the repair. If you have not been able to pick up your boat, spend the money and hire an attorney. Was there a written agreement or word of mouth "fix my boat" type of deal? What state are you in? If you did not agree or sign any type of contract or service agreement, I think that they would have a hard time proving you authorized the repair. I'll be interested in seeing this thread develop. There are a few attorneys on the board and hopefully they will help clarify. Good luck!!!!
