Flooded 97 GSX

[BigAl57]

My Seadoo flooded while it was in the water and I couldn't get it started. We have a rocky shore and I couldn't get it up on the seadoo ramp on my own. Bilge was full. Once I got it on the ramp I found the original problem for not starting. I repaired the wire in the electrical box and then I took the plugs out and turned it over until the water stopped shooting out. There is a mist shooting out now. I have sprayed the cylinders with the seadoo fogging spray. Took cover and spark arrestor off carbs. I put a plug in and tried to turn it over. Almost but not quite. With both plugs in the engine almost doesn't turn over. With plugs out it tries no problem. The milky fluid on the plugs tells me there is still water in the crank case. Is it possible to get the oil out and replaced somehow without pulling the motor? I would have to tow the machine across the lake to get it on the trailer. I am guessing the difficulty with cranking the engine is because of the water. Any help is appreciated.

This is not my info but makes sense.


The first thing to do is remove the spark plugs and the pulse tube feeding the carburetor.

On a Sea Doo personal watercraft install the spark plug wires to the test terminals. Other PWC makes install a spark plug in each spark plug boot and lay them on the head away from the exiting water and fuel.

Using a shop vac, vacuum the water from the exhaust system by placing it in the exhaust exit using a rag to help create a vacuum. Some exhaust exits are hard to access; you may have to remove some of the exhaust hose to vacuum the water from the engine.

Vacuum the water from each spark plug hole, holding the throttle wide open, doing this will exit a majority of the water before trying to crank over the engine.

Re-install the spark plugs and while cranking the engine still use a vacuum at the exhaust exit, this will assist exiting the water from the engine during cranking.

If the engine starts and dies, remove the spark plugs, blow the water off of them, install them and try again and again, until it starts. This usually takes about six times.

After the engine starts and runs, either install a flush line or ride it at the lake for ten minutes. This will dry the engine, completely.

You don't need a vacuum.

Since you have the majority of the water out......
With the plug wires grounded and the plugs out crank it with your thumb over one of the plug holes. This will create pressure and vacuum and bring the water up from the crankcase and into the cylinders. Do this with both cylinders until you don't get any more water out.

You need to let the starter cool between cranking so you don't ruin it.

When you think you have all the water out this way put the plugs back in only finger tight and a little premix down the carbs.

The first few times it will crank and not start as some remaining water will bridge the sparkplug gap. Since you left the plugs finger tight remove them and blow the water off that is bridging the gap. You will probably have to do this a few times.

Eventually it will sputter back to life. Once it is running tighten the plugs and go ride it for at least 30 minutes to burn the water out of the engine.

Finally fog the crap out of it before storing.
