Started having trouble with my throttle controls sticking in the wide open position. It feels like something is stuck or binding inside the control box. I believe it is the standard Mercury Commander, side mount control.<br /><br />I have lubricated the cables at the motor end, but can't see how to access anything on the control box. On my last motor you could pop the plastic neutral button off, remove the handle and access the screws for a cover plate on the box.<br /><br />I just can't see how to access anything on this Mercury control.<br /><br />Any ideas
