The cost of a jet ski can vary depending on several factors, such as the brand, model, features, and year. On average, a new jet ski can cost between $5,000 to $20,000, while a used jet ski can cost between $1,000 to $15,000.

The price can also vary depending on whether it is a stand-up or sit-down jet ski, with stand-up jet skis typically being less expensive. Additionally, customizations such as high-performance engines or aftermarket parts can increase the cost of a jet ski.

It is important to research and compare prices to find the best deal that fits your budget and needs.
