203 Vortex steering nozzle bolts

[Bushmi11s]

I had installed a jet boat pilot thrust vector on my 203 Vortex VRX a month or so ago. The top 13mm bolt came loose and fell to its water grave so now my steering Nozzle is loose. The bottom is still bolted in thank God. I know it’s a 13mm bolt but does anyone know the thread pitch by any chance?

did you ever find this out? I installed my thrust vector last month but didnt have to remove the nozzle bolt. The plate that goes under was able to slide under it without loosening bolt/nut. Definitely improved steering. Did you recognize if the sides of the thrust vector touched the reverse gates when turning completely one way or the other? Mine did so they advised me to cut off part of the plastic edge where the spring is that holds the fins down.
