    2008 175 Optimax - Rev limiter

    Gentlemen,

    I have been having an issue with an alarm going off at 5500rpm. Smart craft gague fault is saying 'engine power limited'. Water pressure is not a problem and neither is engine temp. I was under the impression that the rev limiter is 5750 for this outboard. Can anyone confirm this? Any other ideas what this alarm could be?

    Thanks
