Yuji Sato owner of SE Speedmagic is a collector of many things related to Jet Skis. One of the things he has in his collection is the featured Japanese magazine (probably a motorcycle magazine) that features a test of the first Kawasaki WSAA Jet Ski. This was back in 1973, 40 years ago when Kawasaki released the Jet Ski product in the market. Photo courtesy: Yuji Sato
