    I posted on 9/6 that my 115 opti gave one beep 5 minutes after start up.
    I had the impeller changed and had new plugs put in. The mech put the motor on the computer and it tested out fine.
    Could it be a thermostat problem? Any other ideas ?

    Sounds like it might be a mechanic problem too.

    I searched a few Merc forms on this problem. Just to be clear. You turn the key. You should get a confirmation beep before turning the ignition. Then you start the motor, run for 5 minutes and it puts out one beep. Then you run ok until the motor is turned off. Same problem occurrs on re-start. Correct?

    I’ll also assume the mechanic did not find any stored alarm codes when you had this serviced.

    If the above is true. You may have one of 2 problems. A bad alarm module. Or a bad CPU. Both can toss an errant alarm without sending an alarm code to the computer.

    You can try to find a dealer that is familiar with these kind of “Weird” problems. If under warranty, you can insist it gets fixed even if they need to send a tech out from Mercury Marine to diagnose the problem.

    If out of warranty. Its an errant alarm with no mechanical failure immenant. Drive it like you stole it and hope for the best!

    Jon,

    That is correct in regards to confirmation beep and one beep after 5 minutes.
    Dealer cleared the codes after I brought it in last time.
    He will check the codes again.
    Thanks for doing the research online.
    Big Brother at work frowns on me doing anything that is not work related on the computer.

    I gotta believe that if something is wrong, it’s gonna beep more than once. I’d follow JJ’s advice.

    I bet it is running lean – you will soon split/crack a reed and then you will be an unhappy man. Could be hot – could be your fuel pump/oil pump.

    Opti’s have been know to to this – especially the 225’s.

    Dealer put a new thermostat in today. Said the old one ran cold.Thats why the warning beep.
    Should be good to go.
