My outboard wouldn't go into reverse but would just click when I took it to the lake. So I unhooked the linkage at home and manually put it into forward and reverse with no problem. So I tried to adjust the linkage to hit both forward and reverse. Next time I take it out it will only go in reverse but clicks when tried to put in forward. So I adjusted the linkage to go into forward and used it the rest of the day. I feel as if this is a problem with the control box not allowing the cable to travel enough. Does this sound correct? If so what can be done? New control box or a part replacement? Is it difficult to do? Thanks in advance.
