    200 2.5 Mercury EFI high idle HELP!

    It has only happened twice now, but today when I unloaded the boat and started the motor up, it seems to be stuck in high idle. Last week it started fine. If I can get it simmered down, then it runs and idle great the rest of the day. It also beeped a couple of times while idling high. Any ideas? 2005 Mercury EFI 2.5 liter 200hp.
