Reply To: QD-17 Shift Adjustment Cam

[frankr]

You ask why the cam is there. Answer is the adjustment is provided to make the detent notches in the vertical interlock bar match the position of the shifter stuff (clutch dog) in the lower unit. Problems occur when wear in the linkage cause too much slop so people start adjusting things to favor forward gear. That’s OK up to a point, but with more wear it becomes so sloppy that the lower unit never goes completely in gear and clutch dog and gears wear out rapidly. Then major linkage repairs become over due.
