[C320-list] Autopilot replacement

[ptormey 4square.net]

I installed the Raymarine below deck ram drive and I'm very happy with the results.

The shape of the rudder on a C320 and the offset of the pivot post of shaft let the rudder be "pushed around" by heav-ish following seas. That makes the wheel pilot unreliable when it's needed most. 

I followed Jeff Hare's instructions from the C320 site. He provides a CAD drawing for the mounting plates. I think you can save a little money by using aluminum for both plates, as the Stainless plate can only be seen at the foot of the bed. 

Fortunately, I already had a rudder position indicator which was cleverly mounted upside down!

After 20+ years my Raymarine ST4000+ autopilot is giving up. 

It has always been a bit jerky and noisy, unlike other units that are more
smooth and quiet.   

Would like to hear what others have installed.

Would also appreciate comments on satisfaction, ease of installation, smoothness of operation, etc.  

Thanks in advance,
