Is insurance required on jet skii's in washington state? How much does it usually cost a month? Is there insurance companys that will allow you to insurance only a couple of months of the year (in summer)? How much do tabs cost in washington state and are they required for both jet skii and trailer? Does it cost to license a jet ski and trailer? If yes, how much? I've tried to find this info on the search engine. No such luck. Thanks
