My Sea Star system has a vented cap in the upper helm (flybridge). You can't see a hole so I suspect it's sintered bronze like someone mentioned. I don't remember if it's shaped differently or actually labelled as "vented".

This is how all Hydraulic steering systems in cars are bled. Usually a few full turns both ways gets everything bled. The fill reservoir will "burp" in the process until all the crannies are filled..

Wow, that is a MUCH more comprehensive manual for my system than the one they sent me.
Thanks!

My Capilano system bleeds quickly.
From about 2’ fwd of the rudder/slave cyl my hydraulic hoses run fwd to the helm never going down or even level. The air bubbles go far enough fwd to reach the straight run up to the helm. Putting the helm hard over pushes the bubbles out of the cylinder and up the hose. It was a bit difficult to do but it was/is worth it. I think there is a lot of boats out there w air in their lines/hoses all the time. I was determined to have a nice responsive steering system. It paied off.

Guess which I chose anchored in the middle of a delivery cruise?

Ouch!
This thread is very informative. Going to check our my system next time I’m in the barn.
