I took my boat to a local repair shop in running condition for a fuel problem.They went through the fuel system and said they had it running fine, they checked all alarms and said everything was working great.They took it on a test run afterwards, and said he took it out about a mile or so
and on the way back, the motor developed a knock. He tore the motor down and seen the block had cracks from where they blew the #2 cylinder while test running the boat. He then called and told me it would cost $3,600 to fix this issue. The boat is now not running and the motor is in pieces. He wants me to pay him $700 for fixing the fuel system and pick the boat up as is, with the motor not running and in pieces. This is a legitimate store front business with license and insurance. Do I have a case?
