20 - 30 psi for normal operation.

We have had great success with maintaining dual stations units at the lower number of 20 psi.

I run mine at 15 psi as that is what Garmin wanted on Autopilot pump

Every thing works great

Mine works great at 5psi. More than that and bleeds down to there after a few weeks.

As always Smitty is correct! Hynautic recommends 25 psi but if you're also running a Garmin Autopilot you'll want a lot loss, below 10psi.

Does lower pressure usually take the ratchet feel out at the upper helm? Mine was really bad until I rebuilt the upper. I haven't tried pressure lower than 20.

No - lower pressure will not reduce friction or a ratchet action out of the helm.

My upper helm has the ratcheting issue, is more difficult to turn then expected and I notice in rough seas I am always turning the wheel clockwise ( I think it's blowing past a seal) .

Is there a recommended place to send the upper helm pump for rebuilding?

"Is there a recommended place to send the upper helm pump for rebuilding?"

I have not used them myself but I know a couple of folks who have use these folks.....

Thanks Smitty- I will try the bleed procedure and if that doesn't help I will send the helm to these guys in the winter.

If you are not leaking, it probably is just the bleed issue.
