Default my jet ski wont start

i have a 2007 Kawasaki 250x with 30 hours on it and the other day i got the ski rope caught in the impellor and wrapped around the shaft. as soon as it happened i flipped it over to see if i could get it out. it was only turned over for about 10 minutes. when i turned it back over half the engine room was filled with water. so i picked it up onto my trailer and drained the water out. and over the next 4-5 days i was getting the rope out. when i finally got the rope out i tryed to start it and i wouldnt start. i checked the dip stick an seen it had water the oil. i drained the oil out and put new oil in and changed the filter and it still wont start. any advice???

I'm only a novice, but this happened to me years ago on a Sea Doo. First of all you turned the jet ski back over in the wrong direction. But you probably already know this.
When this happened to me, I also had water in my cylinders. I removed the plugs and turned over the engine - water came out the plugs holes. I left the plugs out and left it in the sun and put fans directing into the plug holes for around 24 hours. It was difficult to dry out the cylinders, but I eventually did. Put the plugs back in and keep trying to fire it up. Hope this helps.

I took the plugs out and blew most of the water out by hittin the start button. I then soaked the plugs n gas to get the water off n pourd a lil gas n the cylinders, put the plugs back n and it would attempt to start but the cylinders keep gettin water in them. And it on land. Would it hurt anything if i turn it over and hit the start button to get the water out? My dad says its a crackd manifold... Should i just bring it to a shop??

I surely would not turn it on its side and crank it, this is a four stroke with a crankcase that has oil in it'. You wouldn't turn your car on its side. I would look into using dry gas to run through it after you have dried it out best as ya can. I wonder if pouring some dry gas 1 oz into the jugs and just turn it over with the plugs out to circulate the dry gas and let it do its thing.Just a thought.

Check your gas tank and fuel lines for water

I tryd today but it blew one of my spark plugs out and just the threads are left still stuck n the head. So i went to autozone and got some kind of tap thing. the threads are opposite of a screw. The guy sed while i turn the thing into the whats left of the plug it will make an unscrew motion on whatever is left. Hopefully this works if not i might have to buy a new engine and that would suck!
