99 xp ltd - flooded now have problems

[tjeree]

have a 99 xp ltd. it flooded. followed all procedures for water removal. now when the motor is killed while water is flowing thru - either in the water or on the fresh flush - the engine won't start again. in fact it won't even turn over, it just makes a clunking sound and the warning beeps. it is not overheating. tried blowing out cylinders appears to have no accumulated water, yet when the spark plugs removed it has water on it. btw, followed the procedures on this board's video. losing my mind, any suggestions?

How did it flood in the first place ???
Was it rolled , swamped or a broken water line inside the bilge ???

I would look closely at the pipe.

trying to get a heavier passenger on the back, rolled just past 90 degrees but not upside down - no water in the engine compartment and just a small amount of water in the engine.

Make sure your battery is good and fully charged, and sand off all the electrical connections, most likely you just don't have enough charge.

It has a new battery, it was replaced trying to correct this problem. It starts wonderfully as long as I blow all the water out before turning off the ski. It acts like its hydrolocked if it is in the water or on a fresh flush when it dies. Don't understand why there's water on the plugs.

[Boris]

You could still have some water left in the cases which get sloshed around or there is water entering the motor through the pipe.
Try tipping the ski over , pull out the plugs and crack it over.
Put a white towel over the plug holes to see if water is coming out.

If you have water in the cases you need to get it out ASAP!!

[tjeree]

turn it over how far? on its side or upside down?

[Boris]

As far as you can get it.
The idea is to let as much water flow out as you can.
By tipping it over you get gravity to lend you a hand.

I don't understand - exactly what happened? Did you get it running after it flipped or not?

[tjeree]

I was going to let a person ride with me. They were heavy and caused the ski to tip over (not turn over, tip over). Water never got in the engine compartment but the motor got some water in it. I got the ski out of the water, followed Sea-Doo’s instructions for draining the ski properly (90 deg. roll over, not completely upside down). Got all the water out, the ski started, it would run okay for a few minutes then it would lug down and die. Once it died it wouldn’t restart. Let it sit a few minutes and it would restart again. I finally pulled the ski out of the water and brought it home. I worked with it until I got all the water out of the engine, at least no more would blow out.

I put the ski on the fresh flush. Tried to start it and it fired right up. Killed the engine, tried to restart it, no go. It only clunked and the warning went off. Checked the plugs they had water on them again. Dried them off reinstalled them and it fired right up. I removed the fresh flush, then killed the engine it restarted just fine.

Put the ski in the river, it fired right up, rode for a while then came in and turned the ski off. It wouldn't restart. After a lot of frustration and a lot of playing with the ski -- the only time the engine will start is when the water is not flowing through the ski when the engine is killed.

I am baffled why this is. I am also baffled why, when you kill the motor with water flowing through it, when you check them, the plugs have water on them.

Any ideas or advice?

OK , that cleared things up .
You say that you went back to the lake and rode the ski for a while. Did you run it hard for long enough to blow any remaining water out of the motor ??
It brings me back to my first post.
Check the pipe.
I don't have a clue as to why this could happen but maybe your pipe is leaking between the water jacket and exhaust.
When you run the motor the exhaust pressure is keeping the water out but when you shut the motor off the water makes its way into the motor via pipe due to the lack of exhaust pressure.
This might explain water on the plugs when you try to start it again.

you have to shut off the water first then the motor , if your shutting off the motor THEN the water your filling the motor back up ,

if you are shutting off the water first then the motor and are still getting water in the motor then you have a blown base or head gasket .

[1fastski.com]

also you could have a leaking pipe gasket , if thats the case fix it before you ride again , you will blow the motor .

[tjeree]

its not like i'm getting WATER in the motor, i'm getting a little bit of water on the spark plug, just enough to foul it. you can't blow ANY water out of the motor, none gets on a towel when you hold it over the hole. and yeah, i know about that fresh flush filling the engine bit - my idiot brother did that to his wakeboat.

I bet you have water in your fuel system. I would drain it and rebuild the carbs.
