Mercury Ride Guide steering adjustment, How?

Thanks bitsamonkey,
Unfortunately, I don't think that will fully solve the problem. It will help travel to port but will reduce steering to starboard. In the first picture you can see that the cable end is already to wall of the notch above the port locker. If I lengthen the steering rod, the steering to starboard will be reduced because the longer steering rod will fully extend the cable end sooner, reducing rudder movement to starboard.
