    2008 Ultra 250x hiccup/surge (stock boat)

    Hey guys,

    Looking for thoughts / suggestions.

    Last two times out with my boat it felt like I had a hiccup in my supercharger, I'd be either accelerating or cruising and would get a micro second cut out and then running fine.

    Changed out the supercharger belt since it was due.

    Went out yesterday, more of the same.... sometimes it ran great, rpm's about 7650 (95 degrees and humid) on my last run back to the launch, it felt like the supercharger never kicked in (no sc whine) and my indicated speed would'nt run past 45, seemed to be running rich (smell)

    My thoughts in order of liklihood:

    -Intercooler
    -Plugs
    -fuel filter
    -supercharger
    -ecm

    Has anyone experienced this, what did you find?

    2008 Ultra 250x, stock boat
    - no water in hull
    - new supercharger belt, tensioned correctly with tool

    Thanks,
    Steve

    ....hopefully fixed (he says with fingers crossed)

    The air box horn on the intake box was loose and all the way out to the point of touching the inside of the hull. ...haven't taken it out on the water yet to confirm, but it makes sense. The boat smelled rich (it being choked of air) It would momentarily cut out when running at speed (likely as air horn would shift its position.)

    I found the airbox and other suggestions from reading the forum, thank you Green Hulk and it's members.

    just tip glue on it and twist it abit to spread it around and it will never move again

    Yes, it was the air box horn, boat ran great on the test run!! Following sirbreaksalot's advice, I will be "locking it down"
