    jetski shutters or vibrates

    2001 sea doo GS

    jetski shutters or vibrates when idling along, reduces as i speed up. the vibration is not too bad but is noticeable, as if the egine is not running smoothly.

    plugs look clean

    thinking of checking plugs for a bad one

    any advice would be appreciated

    check for something wrapped around the driveshaft, like a plastic bag

    make sure your mounts aren't loose or worn

    717s idle pretty rough. Is this a change from how it was or has it always been this way for you?

    I think I'd be looking for one or two strands of sea fauna in the inlet, probably half way in the pump, and hanging down just thro' the grate.

    They can be rough, and 717s will shake your nads off in a no-wake zone. Still, he may have something wrong IF is suddenly worse than before.

    vibrates rougher than before

    It is my first jetski and it's always idled a bit rough but this is worse.

    I will check for foreigh matter per advice - it does run fine as far as I can tell.

    I will check engine mounts.

    Would making an adjustment to the idle speed on the carberator be something to try?

    Thanks for advice!

    Increasing idle can reduce the shake, especially if it is currently too low. it should be 1500 in water and 3k out. Need to find a Tiny Tach if you don't have one as I remember these models not having a tach?
