Hello, I have an '02 IP420 with the original (i believe Raymarine Type 3) hydraulic ram autopilot drive. it will work for a while, but after about an hour or so I get error. Note the error comes up as rudder response failure, but that may be from the newer electronics (Simrad AC42 Autopilot), and not the original error code from a Raymarine unit. We are currently in St. Petersburg, FL. Looking for repair and/or replacement suggestions. As far as i can tell, this is the original AP Ram Drive, and has likely not been serviced.
Thanks!
