Not real sure about XLT 1200. But you need to talk to Ernest T. He is the go to Yamahaha specialist he really knows his stuff. If he doesn't get back to you send him a private message.My son was riding ours the other day and he got an alarm light but no indication on the cause of the alarm. Now it want crank. It displays "Start" on the display but nothing happens. What might be the problem.
i had the same alarm. when i pulled the exhaust apart, the cat element had come out of its housing and slid back. it had mangled the exhaust temp sensor. i replaced it with the d plate and chip. its not real hard to do. if have you a metric socket and wrench set, you can probably do it yourself. got to denniskirk.com for the parts.I just purchased a used 1999 Yamaha 1200 XL. We took it out for the first time today. After running for about 10 minutes the EXHAUST alarm sounded. We went to shore and looked at the ski. Nothing seemed to be hot to the touch, only warm. We restarted and after about 10 minutes the alarm sounded again.
The ski ran great. The only issue I could not understand was that there was NEVER a stream of water shooting out the ski on the left side as indicated in the owners manual. I checked the tube and there is no obstruction in the tube or outlet. There is plenty of water shooting into the air and out the pump from the rear of the ski. The ski always starts right up after you clear the alarm. It runs fine even when the alarm is sounding.
I called the dealer and he advised that maybe the cat/con is plugged up. He said that after a 100 hours the cat/con tends to plug on these units. The ski has 138 hours. He also said something about a D plate or something like that. The dealer does not work on units more than 10 years old. If you know who could work on these older units near College Station, TX I would appreciate a recommendation.
