Kawasaki has a 310 horsepower PWC on sale and it costs $16,000. That is expensive in my opinion. Now this jet ski goes super fast and looks like a lot of fun, but how many people are willing to spend that amount of money on a PWC. You could buy a car with that money! Or 3 Sea-Doo Sparks.
Sure the Ultra 310 goes faster than the Spark. If you jam the throttle open you will fly off the back and stopping all the sudden will slow you down from 65 mph awfully fast.
Is it worth it? Three times as much money to go faster?
I don't think so.
