My boat has a 1985-1987 90 HP Mercury 2 Stroke outboard on it with quicksilver throttle control. This past weekend the throttle control bound up and I could not put it in reverse or drive... so, i pulled the control off from the boat and got it freed up and working good except the center neutral button fell out and I have no idea how this is to be installed back into the control set up. Because this fell out I could not start the boat (Neutral Safety Switch). I do not know the exact model of this control either but hopefully someone in here can help because I'm desperate. I do not have power trim either
