Rudder relocation due to change in proprotation

I have changed engine,gearbox and prop in an 80´s SkiNautique,
which prior was reverse rotation, the manufacturer will not give me a clue as to new location. Are there any guidelines or specifics as to how much to move and to which side in relation to the prop-shaft, so the boat will not tourque around it´s own axis. I am sure I am not the first to have done the switch,,,any help wil be much appreciated

 

If the existing set up worked ok before the rotation change, why not measure how far off cntre the rudder is and 'simply' move it the same distance to the other side?
