Sea doo spark has 250-260 hours on it its the 2014 2 seater. Over weekend was riding and it ran out of coolant. It did not give me a warning light and ran fine. Shut if off tried to start it later in the day and it would not start or turn over. Took it home took top off that when I realized it was out of coolant. The motor is locked. I can take a pipe wrench and turn the shaft 1 revolution in either way but it wont go farther than that. Not sure where I should start looking to fix this. Any ideas will be helpful.
