steering wheel jumps
I have hydraulic steering. The wheel seems to "jump". It doesn't impact steerage but it's a little unsettling. It's the same, at the dock or underway.
Any usual cause??
Many thanks, as always

Sounds like air in the system that needs to be bled out.
Have you tried bleeding?

I agree, air. Bleeding isn't particularly difficult; requires two people and a little patience.
Best if one of you has experience. When I installed my autopilot, I had the assistance of my son the avionics technician, but the actual process is pretty simple.

Interesting - I have never had any help bleeding my steering systems.

I can be done alone, I've done it, the marina techs do it.

Yes. I could have been more clear. My system has three pumps and one reservoir/filler. Hard to exercise the system while adding fluid.

We have always had two stations with autopilot and one reservoir- a hynautic system.
I have rebuilt a half dozen of the steering station pumps and bled the systems over the years while on a mooring ball with no help.
Here is a good link on how to rebuild the pumps with another good link at the bottom on how to bleed the system.
