Yamaha alarms??

[outtabounds]

Had not run the boat for about 2 weeks. I started her up every thing was fine. Took her out after 2-3 minutes it seemed like all the alarms went off at once, low voltage and oil on both engines and the single main gage. I shut one engine down there was still one alarm going off . I restarted the engine shut the other engine down and then restarted that engine and no more alarms. Any ideas . I figure it must be a short somewhere but where do I start looking?? By the way the engines are 1993 yamaha 200hp .

Hey Outtabounds, I can't help you solve the problem but... I have twin 250's, '05 models and have the same problem. Haven't been able toget any real advice. Posted my thread two weeks ago. Couple of guys suggested watter in fuel sensors but I disconnected those and the alarms still scream away. I figures there is consolation in numbers. Good luck... if you get it figured out let me know. Oh, I have a certified Yamaha Technician comming tomorrow for a look see.

Hey Outtabounds, I had a simelar problem with Yamaha F250's as it trunes out; lightning had danced on the Grady. I solved the problem by changing the ignition module and one of the electronic control modules. The ECU's are on the engines. Now, I just need to find outwhy the AC stopped working.
