Brought my boat there for 15,000 dollars worth of motor work and when I went to pick it up about a year later, they treated me so badly! I wanted to clean my boat before it went in the water so I asked if I could,they said sure. As I was cleaning this truck pulled up and started swearing at me telling me to get the f down off the boat! Multiple times! And the service person also was swearing at me because of a storage bill that they said I would not have! I will never go back there. And the two people swearing at me where the grandfather and the father the two owners! The son was the only nice one there besides the help.
