Which motorcycle company introduced the Jet Ski?

rayvan, I suggest you read the description again. The patent for the invention of the jet ski belongs to an Australian.

The stand up Jet Ski was very fun, riding backwards, "submarining" (where you would force it under the water while moving) and "jumping" the wake of boats on a lake brought much joy.

I love my Yamaha Super Jet!!!!
