I am trying to find if there is computer diagnostic software for the Kawaski, Yamaha, or others available to the retail market - for non dealer repair shops. I found some info on a Yamaha engine dignostic that would work on the watercraft models also, but nothing else so far. It is a program that you install on a laptop computer and use cables to hookup to the watercraft to try and isolate what the problem or issue is. Does anyone know of where you can purchase or a lead I can use to track it down? Needing for repair of Kawasaki brands right now for a friend. Please would appreciate any leads or help you can give me.
