    I have a 2000 Sea Ray 340 with two 7.4 engines. I went out yesterday and as soon as I got to 2,200 RPM a buzzer went off near the instrument panel. As soon as I went under 2,200 RPM it stopped. I tried again and as soon I reached 2,200 RPM it went off again. I cruised around at 2,000 for several hours and everything was fine. I found out that it was due to the starboard engine. Engine temperature and oil pressure were normal.

    I would appreciate any suggestions on what it could be.

    Thanks.

    Have you looked at your drive? I've never had V-drives but have read they have a temp sensor that can trip the buzzer.

    Thanks for the suggestion. I do have v-drives but I have no idea how to check if this is the issue.
    I hope some expert will explain.

    2000 should be a very basic limited system.
    Overheat
    low oil pressure
    low drive fluid

    Alarm for all 3 is triggered through a ground wire.
    locate all 3 of these locations and disconnect them 1 at a time while in the alarm mode.

    Does anyone know where the buzzer is located on a 2000 340?

    Under the helm/dash by your key/toggle switch. You hunt that if it's not going off, not if it is.
    Follow my advice in post #6

    Thanks, scofflaw. I'll try that.
