What jetski do you have? Is it a 440, js550, or 550sx? There is a hull identification number on the back right corner if you are standing behind the ski on the flat surface of the bond line. Or take a pic of what you have and I can figure it out. Take a pic of the engine bay if you have a motor too. Impellers are built to the hp of the motor and pump type. I need more info to know what you have and what you're trying to accomplish.
