This coupling nut on steering cable keeps coming loose ! It actually came off 3 trips ago so I unbolted the exhaust , loctited, and tightened it up. Used it twice last season. While doing maintenance today I noticed its loose again!! I put vise grips on the opposite end and tightened it again but it seems like maybe something is wrong. (As in it shouldn't be backing off) it was a brand new cable when I restored boat few years back. Dont mind dirty boat I just uncovered it after 6 months
