Hello all I was just given this jetski and was wondering maybe someone could identify it? I know it's a Kawasaki and the engine has TC-530b-GS00 on it. Some info would be great so I could get started on getting this ready for the water.

Hope this is enough to help someone identify it.
Looks like there has been some mods done to it, the exhaust, head, air cleaner, jet intake and plate under water jet all seem to be after market?
Any help would be great!
Thanks,
Mike K.
