Hi, does anyone know if the rudder stops can be adjusted?

The mechanism for the Jefa autopilot is problematic at the hard over extremes. Hard over to starboard the draglink can touch the drive unit lever arm. Hard over to port and the rod and lever arm are inline, and they can jam.

If I could move the stops in by a few degrees, both problems at these extremes will be fixed. Many thanks.

The rudder stops are at a fixed position, I believe.
It is very important that the draglink is mounted in the inner hole, and that the angle between the arm and the draglink is 90 degrees, when the rudder is in the middle position. There are a lot of drawings at the Jefa homepage.

Hi Captain Cook, thanks for your reply. Apologies for the delay - I've been away. Interesting... My lever arm only has one hole, but the arm is shorter overall. However, my draglink appears to be attached to the arm at a similar position to yours - based on the length of the slot, and the position of the small hole and the position of the attachment point. I'll contact Jefa for further advice regarding the set-up for 350s specifically.

Hi

My 370 also only has one hole. Think it has been cut to avoid confusion.
