How critical is the rubber seal around the prop hub

[coosarunner]

I have a merc 650 with a leaking foot. I pulled the prop and the two seals and one looks indented. Everything is still pretty greasy and the foot oil wasn't that foamy. Should I go through the foot? Impeller and the rest of it or just put new seals in it and run it. The rubber on the inside of the prop hub is worn as well.Any suggestions?
