The shift cable is not broken, when disconnected from the motor it seems to move normally. Sorry, seems most of my post didn't post..
The boat has been setting for the last 2 years on the lift. Got it prepped to put back on the trailer, backed it out of, and went to put in forward gear and it's like it's in neutral, reverse fine but not going into forward gear. It has the top mount binnacle and has always been somewhat stiff in shifting.
I pulled the shift cable off the linkage at the motor with the control in neutral and there was some obvious adjustment as it didn’t really line up properly. I did adjust it in a bit (5 turns) to line up with the motor in neutral and put it back on. Now it will go into forward gear but not reverse. I tried to adjust it a few times but no go. I did disconnect but I really could not get a grip on the linkage to see if it would shift by hand (no cable attached). Should it be easy to shift without the cable?
