2005 RXT Jet pump housing nut

[vmax1994]

I am the second owner of a RXT. When taking apart the pump to free a stuck rock, I found a missing nut on the stud for that fastens the jet pump housing to the hull. I was working at my cabin and decided to bring it home to finish repairs. My trailer bearing blew out on the way home so I had to leave my trailer and RXT at a shop. Now I don't have the Seadoo so I can determine the size of the nut that is used. Long story for a simple question....does anyone know the size of the nut for the jet pump housing stud?
