No Vin number on hull, i wouldnt be surprised if this one was hot.
No paperwork = no good in most states.
Lets just say I just bought a 84 JS550, I have old regs, Statement of Orgin, but since the previous owner refused to title it for me the state wont issue me a title. So I paid another $50 for a new hull with a title.
Most states have crazy hard title laws on PWC.
