So I'm giving the boat a good going over before I hit the lake, and want to check the coupler alignment.... Anyways follow the instructions I found on the site, but when I loosened the bolts ( I actually took them right off) nothing happened. I tried knocking the coupler to separate them tried going underneath and pulling on the shaft, but nothing, no separation to be able to check the alignment. Any Suggestions, or should I not worry about it?
