Probably.
When you flush the engine it should always be running first. Once it is running, then you can turn on the water and let it circulate through the engine.
There is now water in your engine. Take the plugs out and roll the ski over on its side (toward the pipe side) or tip it up on its nose. Hopefully some of the water will drain out at this point. You can then bump the starter. Beware, that if the ski is "hydrolocked", you run the risk of bending a rod. If the engine will crank, then crank it and let the water spray out. At some point the amount of water spraying out will diminish and you can reinsert the plugs and attempt to start the ski. You will probably have to repeat this process many times befor the ski will fire up. If you have some WD40 you can spray the plugs with that each time you replace them to displace the water that will have been sprayed on them.
Anytime you flood a ski, the best response is to get it running as soon as possible, then ride it for 20 minutes or so to make sure all the water in the engine has been forced out. In your case, if you are at home, I guess you could put it back on the hose (AFTER IT IS RUNNING), and run it on the hose for a while.
Good Luck!
