    01 XLT1200 just dies

    My friends 2002 (not a 01 like the title says) xlt1200 just started acting up at the lake yesterday. While cruising along and punching the throttle the ski will just turn off completely no hesitation or anything just dead. It’s not stalling out like a fuel issue, it’s like hitting the kill switch but the gauge display goes off at the same time unlike when u turn it off. It then takes a good minute before it will start back up again. This happened about 5 times before we pulled it out of the water. We first looked at the fuel filter which had a bunch of junk in it. Plugs looked good and clean too. Cleaned out the filter put it back in the water and same problem. We then looked around some more and found the positive lug on the starter is loose and can spin freely inside the starter. It doesn’t appear that anything got wet inside the ski no water anywhere. Could the starter be the cause of this ski just going dead in the water? I wouldn’t think a bad connection on a starter would be causing this but before he drops it off at the dealership I thought I would check around here. Oh and from what we know this ski has just a d-plate mod. thanks

    It's overheating, the Cat Con gets hot and the sensor shuts down everything. Remove the Cat and replace with a D plate and sensor chip.

    Check those oil lines on the carbs make sure there tight, replace the cable ties with crimp rings.

    And yes check all 3 cylinders for compression, depending on the age should be some where between 110 - 120 psi on each.

    Clean / rebuild all 3 carbs

    The oil line makes sense. there was some oil in the back near the tunnel, decent amount too. He thought it was from last week when he over filled the tank and just forgot to clean it out. Defiantly take a closer look. thanks

    it has the d-plate but i dont think its chipped just unpluged

    That's your problem, check the #3 cylinder oil line, if it loose there's a good bet that the #3 cylinder is shot.

    You'll have to remove the exaust stringer to get at it.

    You need the chip or the ECM won't funtion correctly.

    #3 being the rear most cylinder correct? that plug was tan but had white specs, the others didnt. oil line plugs into the carb? sorry the wonderful world of pwc is new to me. we are mechanically inclined though
