200 EFI alarm

[MarkW]

I don't know much about the 200's but I know alot about my Merc 225. I have done 90% of the work on this motor myself. My engine runs the warning buzzers through one of the computers. I have had the buzzer and/or lights go off and it has always been for a problem other then the computer. I don't believe you have just a "module" for that beeper.
I would definitely talk on some of the other boards and get some expert help. Engine parts can get VERY VERY expensive. Good Luck with it.
I am going to check my 225 Service workshop manual and see if I can find any other info for you.

Yep---225 workshop manual says the same thing. Says water in fuel will beep 4 tmies with 1 second intervals and stop for 2 minute time periods.

If I were you, I would just replace the fuel/water seperater filter, mainly becuase it may need one and it also comes with a new sensor. They are only about $20.

Good Luck.
