    08 rxpx locked up

    Ok so here it goes was riding the other day cruising around 35 and the ski just shut off on me and would not crank back over, starter throws in then just groans and wont spin. Pulled plugs still nothing and no liquid in cyl, I pulled the pump and tried to turn the engine over by hand and its locked up solid. I started taking the ski apart and noticed there was no coolant in the resivoir and it was all in the water box. Oil is perfect not milky at all, pulled valve cover and intake mani and all the valves look good and no sign of damage timing chain seems to still be on as well. Pulled the sc and that spins freely as well. My question is what should I check next and does anyone have any idea what happened. Ski is all stock and had 80 hours on it. Any info is greatly appreciated

    Thanks!

    pull the pump and check that.

    Maybe dropped a valve? and it punched a hole into the head coolant cavity???

    If the pump spins free then pull the head off.

    pump is off still wont spin over. must be a exhaust valve if one dropped bc the intakes all look good. Are 08s known for this?

    no the 04-05's and some 06's are known for that.

    I just dropped a valve not that long ago. Sucks!

    Ok so if it did drop a valve if may be locked up due to the piston being at the top of its stroke with the valve smashed threw the coolant passage. Sounds pricey haha

    Cool

    That's not a normal thing for a 08 x model ski.
    Those things are made to run 8k+ all day long...


    Has your ski ever been hydro-locked?

    Do you know the skis history of maintenance?
