It would not start so we pulled the spark plugs and when it turns over it turns over weak and some water comes out of spark plug holes. What do we need to do?? new to jet skis and have no Idea!!

    I am also in the same situation, ironically on 8/9/15 1998 kawasaki zxi 1100 took on salt water, had to have it pumped out and brought back to the boat launch... We have tried the same thing, pulled plugs, turned it over, and it was like geysers out of each cylinder...We had gotten to the point of it alsmost being dried out a couple days ago. last night we turned it over and just a little mist came out...Today we put the plugs back in, and tried to get it to start, but to no avail! Pulled the plugs again, once again tried to turn it over and more water came out out the cylinders.. Where is this water coming from? We took the air box off, its not coming from the intake? Very frustrated at this point and looking for advice as to what to do next...Any help is appreciated!

    I hate to be the bearer of bad news, but the best thing you can do now is part it out. Your engine is toast.

    Salt water is extremely corrosive. Salt water in the crankcase will destroy the crankshaft & rod bearings in a day. Yes, it may turn over now, but the rust has already formed. In another 10-20 hours of running, the bearings will seize and the engine will either stop running or a rod will break and come out the side of the crankcase. The carbs will have to be rebuilt, but they're probably full of corrosion, too. Most likely, the electrical box has water in it and all connectors are corroded. The stator cover may have leaked and corroded the electrical connections there. Starter could have corrosion inside, etc.

    On the positive side, the jet pump should be OK.

    Thanks for the input...As of now we have decided to pull the engine and rebuild it...Its been flushed out, but as far as the rest goes, yes the cdi had been submerged and when taken apart it looked like it had previously taken on water...Some connectors had corrosion that we found...But at this point in time new module parts, wiring harness, gaskets, etc. have been ordered...Already put too much into the ski to part it out at this point...Besides why part it out when we can tear it down and rebuild it..

    Do you know what it costs to rebuild/replace the crank?

    A quality rebuilt crank is $600-700+. Hotrods also has a new one that can be found at various vendors on eBay for $700-900. I don't trust SBT, so I spent the money on a rebuilt one that my machinist trusts.

    Well have looked at some parts at kawasaki parts house, and just for the crankshaft-comp alone is $1100.00, Yikes... so at this point sometime this week its going to be more like damage control, yank the engine after work and see whats savable, Dont really wanna junk the jets ski, but not sure if its feasable at this point to keep dumping money into something that we have only been able to ride once..Mind you it got sunk its first time we had it out...

    When you tear it down, take a really close look at the needle bearings on the rods. I don't know if you can see anything on the main bearings, as they should be sealed. If you see any rust film, that's bad. It has started microscopically pitting the metal and will get worse. Pitting and wear in bearings increase exponentially. You start with just a little bit, which builds to a little bit more, which builds to a lot more, which finally blows up. You won't see the effects of the damage right away. But 20 hours later when you're miles from the dock, you'd better have a paddle...

    Guess they had to leave out one of the thrust washers to keep that 'tighter tolerance'...

    Well so far looking at the needle bearings they seem fine...lets see if I can get a few pics in here..Everything is soaking in wd40, and gonna be cleaned, but the crank looks good, the cylinder has a touch of rust, nothing so far the hasnt seem to be able to be cleaned out.. counter weights look like crud though, heavy build up...might get a tub and soak stuff in diesel,not sure how much farther we really want or need to tear it down to clean it up...And what is the deal with SBT cranks? are they good or bad or what? cheap? inexpensive?
