2003 Yamaha Waverunner 1200 XLT wont shut off

SOURCE: Overheating YAMAHA XLT 1200 jet ski

you may have something clogged in a water passage but more than likley u have a bad sensor the sensor is located on the main exhuast if you go on the right side of the ski and look in the engine compartment it will be located at 9 oclock u will see it sticking out of the exhuast with one wire comming out after u run the ski and the buzzer goes off pull the seat and see if the engine is really hot if u can not touch it will be hot but it has to be very hot for the sensor to pick it up if u can touch the motor and exhuast it is a bad sensor
