    FX HO only pulling 8000RPM

    We towed my 2006 FX HO home after dark with the barge at a very slow speed, next day 8000 is all she will pull, I can see nothing in the pump, air filter is clean, I have put the ski in L-mode and back to normal, disconnected the battery and reconnected, oil is fine, engine does appear to misfire, just acts like it is governed. There are no engine warnings, idles fine, starts fine, I am going to put in a set of plugs this week even though I have my doubts. Has anyone seen this scenario or have any ideas?

    FIXED

    Turned out to be the plugs after all, glad it was that simple, but still is strange the way it all happened.

    I have an 08 FX HO with the same issue, I'm putting new plugs in this weekend, I hope it solves my issue too!

    FX/FX HO eat plugs like candy

    This is a very common issue and you would not think spark plugs would cause this issue but they do.

    New plugs have solved many a running complaint.

    Someone should really sticky the two most cited issues with MR-1 Based yamaha engines.

    1. Spark Plugs

    2. Overfilling the oil.
