    250x Water ingestion. Spark plug broke in half??????

    I left the plugs out when I drove it and ingested water...stupid i know make fun if you want but it happened. I took the catch can out and intercooler which drained milky oil and water. There was literally no oil left when I started working on the machine because it had all drained out into the hull and than the lake. is that unusual? anyways back on topic when I got to taking the sparks plugs out number 3 was hard to get out. After they were all loosened I started taking them out when I got to #3 I took it out and the bottom half of the threads and everything was gone. Looked like it blew up halfway up the threads. THE ENGINE WAS NOT HOT WHEN I TOOK THEM OUT. anddddd plug #1#2and#4 were all fine just blackened a little on the tips. Here I stopped before trying to start to blow and water oil mix out to ask. Should I try and blow the water out? What could be wrong. Where the hell is the rest of my spark plug. anddd how screwed am i? thanks

    Your going to have to take the head off the motor to get the rest of the plug out.
    I had a kawi that broke a plug and that's how my mechanic did it.
    As far as the water I wouldn't crank it till you know that the rest of the broken plug isn't in the cylinder.
    I hope your mechanically inclined.

    Spray the open cylinders with spray oil. Wd40.
    Kawi skis are known to break plugs.
    You should use anti seize on the spark plugs so they don't stick.

    what a load of crap

    all alloy headed engines that have metal spark plugs and that have spastic's over tighten or dont apply never-seize have the potential to break plugs , not brand related at all

    Waz

    may as well say only seadoo hull crap them selfs.......when we all know other brands can and do have issues

    It's a fact the plugs that Kawi uses are thinner than other manufactures.
    Which makes them easier to break.
    But all plugs should have anti seize no matter the manufacturer.
    I've had and seen other Kawi skis with them broken.

    talking about miss-informed

    all plugs of the same thread and sealing face design by the same manufacturer are the same thickness in the constriction

    its only the metals used and length they protrude into the cylinder ............and a FACT is the same plug as the kawi uses can break in a yammi to because of the usless person fitting as I mentioned before

    funny thing is I have been fitting spark plugs every day of my working life ( 25 years ) and when done CORRECTLY plugs dont break off

    yes I have had 1-2 plugs in that time that just break the thread off ( shit happens factor )..... but they also just wind out by finger, because it was a construction fault and not caused by tight threads or over tightening, and in that case the plug dont care where it was fitted too
    and I am not saying others have had a bad run , but its not brand or ski focused

    so please do try to paint all plugs and skies under the same mumbo-jumbo false info

    Yeah I have warranty left but the dealer probabally dosnt cover that do they? I have an appointmet but its no use me driving and hour and a half to the kawi dealer if they wont cover it i put the other plugs in and just set #3 in the hole didnt tighten obviously and everything will be put back on but am I better off taking it apart myself?

    you still need to drain the motor of the sludge you have created best you strip the head off and start getting that water out asap before further damage sets in.
