A reliable autopilot is great to have onboard because it gives you opportunities to rest your arms and/or eat while under way while still keeping an eye on things. So, when something doesn’t feel quite right with the auto pilot system, don’t wait to fix it. Practicing easy, preventative maintenance on a regular basis will prevent costly autopilot repairs—or replacement—later on.
Servicing Your Wheel-Drive Autopilot
Regular fresh-water flushing and an annual hands-on inspection of your wheel-drive autopilot unit will keep your steering reliable on passages—and save you from hunting ball bearings across the cabin sole

Just went through doing some maintenance on mine! In my case the clutch was disengaging. As an often single hander that’s def a problem
Check the transmission cable as well, making sure it properly adjusted and tightened. Also for sure, proper fluid level is important.
Oops I was responding to another comment on transmission issues
If the clutch disengage, it is most likely the tensionner that is too tight. Untighten it a few clicks and see if that helps. Adjust as needed.
Good instructions. I had similar problems, including the plastic mounting studs the screws go into breaking off (I forget the repair; I recall tapping and making some small bushings).
I also recommend getting a spare belt. It’s not breakage; eventually, simple wear will result in slippage. They’re cheap.
Thanks Drew always appreciate your feedback.
Perfect timing! My steering froze today, with the rudder in a moderate turn to port. Fortunately I was not far from my harbor and a very capable friend was able to tow me back (awkward with the rudder frozen in a turn!). I checked everything I can get to- chain sprocket in the pedestal and quadrant at the rudder head, so I will pull off my wheel with the Raymarine autopilot to service before turing the problem over to the boatyard. Thanks for the clear instructions and video!
Glad you had help getting back safely. Thanks for reading and sharing.
I have tried generic replacement belts. They slipped – I tightened them and they broke within weeks. The original grips the drum much better and appears to handle the tension better.
Hi Gerard, yeah forget generic belts. They don’t last and are made of weaker material. The original is more expensive but will last much much longer.
Great article
