    Yamaha ex sport issues

    Most of the time my ski runs fine, once in a while it start vibrating I take it to shore shut it down for 5 minutes start it back up and it run ok. I check the impeller it was ok. The ski has about 4 hours on it. Does anyone ever seen this before.

    Before attempting to remove weeds or de-
    bris from the jet intake or impeller area,
    shut the engine off and remove the clip
    from the engine shut-off switch. Severe in-
    jury or death could result from coming in
    contact with the rotating parts of the jet
    pump.
    If weeds or debris gets caught in the jet intake
    or impeller, cavitation can occur, causing jet
    thrust to decrease even though engine speed
    rises. If this condition is allowed to continue,
    the engine will overheat and may seize.
    NOTICE: If weeds or debris gets caught in
    the jet intake, do not operate the water-
    craft above trolling speed until they have
    been removed. [ECJ00654]
    If there is any sign that the jet intake or impel-
    ler is clogged with weeds or debris, return to
    shore and check the intake and impeller.

    When crap gets in your impeller it will do that and usually killing it and restarting will clear most debris unless it is really bad then follow directions from above posts.
