They were developed from the Japanese (Sea Sleds) were a form of assault open-operated ( by something akin to frogmen) submarine,normally one man. Sea sleds used peroxide torpedo engines and did not require an oxydizer- built into the fuel. Thar is my guess.
The year that jet ski's were invented was 1967. Jet ski's were invented by Clayton Jacobsen II of Arizona and they are considered the most entertaining aquatic activities.
the person who invented wakeboarding was Thomas.camilleri
Up to a point evolved out of Japanese Sea Sleds or open midget submarines.

You need a boater's license and a jetski license in order to operate s jetski legally.
The average price of a Yamaha jetski watercraft is about $12,000 excluding the onces that are sold secondhand. Prices can be found online on the Yamaha waverunners website where different variety categories of jetski can be found with different price ranges.
Top Speed? We have the exact same model, and the top speed ever achieved on it was 73 MPH. It's a FAST jetski! Not to mention that model is the first ever three-seater jetski! Hope this helped! :)
in Wisconsin if you are under the age of 12 you are not allowed to drive a jetski at all. You are allowed to ride on the jetski but not to drive it.2. At ages 12 to 16 years old you must have taken and passed an approved water safety course and while riding the jetski have in your possession the water safety course certification (like a License). also fart fart fart
On the side
a boat, it is obvious
The control valve purpose is only to release any water from the crankcase if the jetski has been underwater, and water got into the engine.
