I have a Seastar Hydraulic steering helm and outboard cylinder. Cylinder is HC5345. Problem is when I turn the steering wheel my outboard does not turn. I have bleed both sides to where no bubbles. Opened each single bleeder valve to ensure it is pumping fluid, and there is. Not to sure what the issue is. I can easily push my outboard each way. Seals on the outboard cylinder have just been replaced. Any help greatly appreciated.

I would lean towards sludge in the helm and or valve stuck open. Rebuild the helm it is not difficult. Also how old is everything, what size motor and what fluid are you using? Does the helm stop (Hard over) or does it just turn and turn. You could potentially have a big air bubble but you would see some response so..... not sure.

If you can push your motor back and forth you still have air in your system most likely. Typically after a bleed you can shake your motor and check. You want no more that 3/8 of an inch of play.

You should hit a "wall' when turning hard port or starboard. Best thing to do is verify what cubic inch helm you have then count your lock to lock turns. 2.0 Helm is 4.2 turns, 1.7 Helm is 4.9 turns, and 1.4 Helm in 5.9 turns. Once you verify all of that it should tell you if there is air in the system or not.

It does sound like air in the system to have absolutely no response. Try to bleed the system again and continue to push fluid through the bleeder longer than you think you need to. Could be a lot of air in the helm pump. If done properly, when you begin to tighten the bleeder fitting, the cylinder should move and be impossible to stop the movement.
