Be careful tightening that. If you read the MCIB report into the sinking of the yacht Megawat, it was due to wear on ther rudder stock caused by a poorly fitted autopilot. ***********************************************
This came to mind here too and not only how the auto bracket is secured but also ensure it isn t mounted on the shaft mid span between bearings where it imparts bending moments......
Fibre glass rudder stock........are you sure??????????
How is the steering quadrant or tiller attached???
