How do tell wat year my old kawasaki 650 jet ski is and wat model???

Question

its orange and a stand up, not sure if its orig colour

Answer 1

On the back of the jet ski, there should be a 12 digit Hull Identification Number engraved into the transom. The last two digits delineate the year (ex. 08 or 97.) Depending on how old it is, this should work.

As for the model, the newer jet skis have the model written on the sides, not sure about much older models.
