We rented a jet ski from Jerry’s for one hour last week. The price seemed to be standard within the area — $ 115 dollars per one hour or $ 90 per one half hour. The kids that checked us in at the desk, explained the regulations, and got us on the jet ski were all nice, but seemed very young. You must have a credit card that does not say debit or is not American Express to leave with them in case there are damages when you get back. Apparently there is also a Wisconsin law that you have to be born before 1÷1÷1989 to drive the jetski. Just a heads up.
