Personal Watercraft and Jet Skis

How do you un-flood a Jet Ski motor?

Depends on the type of flooding. Hopefully the gas flooded and not the water flooded. If it's flooded by gas try starting it with throttle wide open. If it doesn't work after a while, remove spark plugs and crank engine over for few seconds (remember to watch out for the spark) Install new spark plugs. If the engine is flooded from water, you will have to remove the spark plugs and crank on it for a while till all water comes out. *I have personal experience here* Install spark plugs and attempt to start, if not remove plugs and keep cranking. It may fire for a second or two. Keep removing spark plugs to dry them off and crank some more. Keep this up back and forth for a while, or till engine fires up.
