When you are considering buying a jet ski remember that you need to make sure you get the accessories as well.
You should make sure you pick up enough life vests for all of your passengers and that you have the proper trailer to transport your jet ski from your home to the water.
You should also make sure to budget for regular maintenance. You don't want your jet ski stranding you far offshore just because you didn't have its oil filter changed regularly.
Also make sure you know what fuel your jet ski needs and how often it needs its tank cleaned.
