shift shaft adjustment for 135 johnson

[Carl]

I was helping my neighbor repair a shifting issue which turned out to be corrosion between the double O-rings on the shift shaft. The shift shaft was completely removed during the repair and we kind of took a best guess at the height for the reinstallation. I think we are really close because in shifts into reverse very well, but it seems to slam into forward and only with a bit of throttle. It makes noise and seems like it just doesn't engage completely in forward. My question - how much of an adjustment should be made? Is this a 1 turn adjustment or 4-5 turns? Also which direction should the shift shaft be turned? thanks for the help
