As everyone here has said, these things are not water tight.... and the possibility for damage is high....

I suggest at a minimum, pulling the jet ski out of the water, and doing a oil change to look for water in the oil.

Most of the electronics should be sealed so as not to be effected by the moisture....

Bring the machine to the dealer is not a bad choice, as they have experience with dealing with just this type of situation. However this can be costly.... However not as costly as running with water in the oil....

now as for getting things caught and tangled in the jet pump... The only safe way to remove them is unfortunately to get the jet ski on land and disassemble the pump, as much as is needed. As was discovered here, the longer the ski spends upside down in the water, the more likely you are to have problems.

Also to note is that towing a disabled jet ski requires some caution as well... I have a fresh water cooling line in mine that needs to be clamped, to prevent raw water from getting back to the engine through the exhaust.
