@ Tom: With the system being pressurized, you mean I still have to spin the helm dozens of times each way? While purging, I got NO air out of port or stbd lines, just fluid.
Don't understand. After looking at this today in depth I can't figure it out.
Upon initial inspection the system had 18lbs pressure (so no leaks).
The upper helm just spins freely.
The lower helm and auto pilot performed flawlessly for the 4 hours use from launch to home mooring.
Today I took a bike pump to boat, pressurized system to 45 lbs, and bled from upper helm. Only fluid came out. No air.
Is it possible that the helm itself is worn out?
Here is a set of pics with pretty good explanations I found on the net about changing seals.
H 50 helm rebuild.
I ordered a set of seals to change myself. Will have to tackle this upon return from the briny blue in two weeks. But this would appear to not be leaking seals but a mechanical issue of the balls and pistons inside the helm itself.
Has anyone else had similar issues? One more thing I will check tomorrow is if the wheel is spinning the helm shaft. It almost felt as if the wheel was free wheeling. It doesn't look like the key could be spit out....... But it is a boat. Stranger things have happened!
