In January 09 I stopped by a recommended boat service. My Yamaha 100hp 4stroke had a carb that the float was sticking open causing gas to fillup a cyl. I asked the owner when would he wanted me to bring the boat in so he could service it. I called back in a few days and he said bring it in the next day (1/28/09). I took it in and gave the owner a note which described the problem again. I stopped back in a week and saw he had taken off the head. He stated the head gasket needed replaced along with cleaning the carbs. The parts were stored in cardboard boxes. I didn't get the boat back until 4/24/10. I never was disrespectful or mean during my 50 or so visits to see the progress made. In fact I used the Columbo personality and just asked questions and volunteered to assist in any way I could. I knew taking the boxes of parts to another boat service company was not going to be looked at very highly so I stuck it out. The boat was left out in an open yard and was in pretty rough shap when I got it back. The owner never once mentioned the length of time it took to repair. I know for sure at least 100 boats came and went while mine sat there. I wrote the guy a $1,775.80 check when I picked it up. The next day I stopped payment on the check. I've sent him notice that we need to discuss further before any monies are paid. The personal property tax alone was over $700 while it sat at the shop. He charged 9hrs labor to complete a 15 month repair. What should I do????
