David,
My Simrad WP30 used to stick badly when disengaged. It stuck to the point we could barely turn the wheel. I thought it might be salt build up. I usually sprayed water into it from the cockpit shower and it would release for a while then start to stick again.
The problem was the belt. I had bought a replacement belt off eBay some years back. The belt was made in France. The French-made belt felt "sticky". I did the research, found the belt was a standard timing belt and purchased a Gates brand belt online from Royal Rubber. The Gates brand belt did not feel sticky. After swapping the belts, the WP30 has worked flawlessly. Wheel spins freely when WP30 is disengaged.
Don't know if your Raymarine issue is similar.

Hi Joe- Have you ever had the problem where it does not release wheel control when you flip the lever? I still don't know what caused that.

It is about 20 times harder than a Rubik’s Cube to get them back in correctly. Raytheon ended up fixing it for me on the condition I never ever call them or send them any parts of the autopilot again.Joe Della Barba Coquina C&C 35 MK I
