Hello, I have a 1995 Mercruiser 3.0 LX with an Alpha II, when I make a turn a rattling noice sounds from the Alpha II. I checked the driveshaft and gimbal bearing and it seems to be fine. Also when I am going forward on the boat it rattles and the boat vibrates I have to adjust the tilt on the Alpha II for it to stop. Can someone tell me what this problem is? Thank You.
