Seal repairs on a SeaStar cylinder?

[other tom]

Anyone ever replaced the seals on the engine-mounted cylinder? I recall some posts awhile ago, I have a SeaStar HC 5345 that developed a drip during our recent keys trip (also trashed the clutch/gears on a yammie lower unit, but thats another story - new one is already on the boat)

Checked the rod on the cylinder, its clean, no nicks or cuts. could it be from wear and tear?....
