Thanks Marc - I'll check the web page for the updated manual.

Just to clarify, the system I needed to rebuild was the Seastar, not Baystar. The new, updated Seastar helm pump has a rubber snap-in cover that keeps the fill plug from being exposed to the elements at all - on the old one, there is nothing but the o-ring on the filler plug keeping water and contaminants out. That may have been where my problem originated - I certainly didn't ever have to add fluid, and I think that would have been the case if the cylinder seals were compromised. In any event, it's fixed now.

Again, thanks for participating!
