Depending on your needs and wants, a jet ski can range anywhere from $5,000 to $15,000. In the $5,000 to $9,000 range you can pick up a typical two- or three-seater jet ski with 110 to 150 horsepower which will propel you to speeds around 50 mph. At this price there won’t be many bells and whistles on these models. But if your budget permits you to spend more ($9,000 to $12,000), the overall build quality of the jet ski improves. Jet skis in this price range provide a smoother ride, offer an average of 200 horsepower and cruising speeds at 60 mph. At the $12,000 to $15,000 price point are jet skis that offer the fastest and most brutal ride out there.
