Anything is possible I guess. I have had them work on my boat a couple of times over the past 10 years and have been satisfied with the work they did. I am not very mechanical when it comes to working on motors or boats so I have to get someone else to do most things for me. I have been disappointed in the outcome several times over the years, some my fault, some the mechanics. Any time you work with you hands and mind you are subject to make mistakes. I guess I am just one of those folks that is glad someone knows how to work on my things and I don't have to buy new every time something breaks. Sorry you had a bad experience.
