Well,,,
If you have run the engine it is HIGHLY likely that you have created damage. In a nutshell, coolant is not compressible. As a result, when you put it into the intake and it makes it to the cylinders and the valves close,,, it is now in the combustion (aka compression) chamber.
So,,, if the engine locked up and did not turn over you may be safe. Remove all of the plugs and crank the engine. But even then, crank it for like a quick second at a time as the water will be like a jet coming out of the spark plug hole.
If the engine did turn over with water in it, and there was more than a small amount of water (as a small amount might pass as there is air in the chamber that can compress and take up the room of the water), then you will likely have damage. Could be a valve, head, or head gasket. Officially you could have a block issue that that is VERY rare as the water is pushed to the top of the block via the piston.
Lastly, if you put the coolant in and THEN realized your mistake. Use tubes to siphon out the water. In a perfect world, turn the ski upside down to further get the water out. If you cannot do that, remove the plugs and LIGHTLY crank the engine.
Once you do get all the water out, assuming there is no damage. You want to run the engine ASAP and let the oil inside the engine do its job. You will need to do an oil change immediately as well as you want to remove the residual coolant from the engine so that once it sits it does not cause a corrosive situation..

Pretty much you have to take the antifreeze out. Doesnt matter how much you put in there, you still need to get it out. There is a small sensor towards the front of the air intake on the bottom facing away from the battery. Its screwed into the intake if you take that sensor out and then tilt the jetski forward with the rear in the air, might go ahead and jack up your trailer from the back and put the front on the ground, you may be able to drain alot of the antifreeze. I had drowned my ski and had to take the intake completely off, which isnt too hard, but you have to pretty much disconnect all the sensors, remove the fuel rail, then take off the 8 screws holding the intake in place. Try the sensor removal first and see what all you can take out.
If the ski has not been started the furthest the antifreeze should've gotten is to the intercooler. And that's only on the off chance that it leaked past the supercharger. My advice is to pull off the air intake hose and see if the liquid drains out.
