[quote=Edchris177]How old is the ball?
Old ones, left in a high UV environment degrade. Buy a new one.
Secondly, look at the cup on the mast base.
Is there a sharp edge, or burr, that is cutting into the mast ball?
Don’t worry about the ball turning. Both my 5.0 & 5.7 do that. As the mast rotates left, it unscrews the ball 1/4 turn, when it rotates the other way, it turns the ball back down.
There may be other issues, but if your rigging is tight, the mast cannot fall off the ball[/quote]
