I've got a 2006 216 Sunesta. On my last couple of outings I've noticed that the steering is off center and I need to keep the wheel a half turn to the port side in order to stay straight. The boats steers fine otherwise. I've had the boat for three seasons and this is a recent issue. I'm going to investigate it this weekend but thought I'd check here to see if anyone had a suggestion on what might be the issue.
