3 propshaft seals positioning?

[roadkill636]

I see some posts about folks adding a 3rd prop shaft seal. I dont see why not.. but I'm wondering what direction is best to put the center one? Inward or outward? To keep the oil Izn or the water OUT?

I put the first one facing in and the other two facing out.

I am not a fan, of 3 seals on prop. shaft. What I think is important, is to emory prop. shaft at seal area. Then almost fill area, between seal lips, with good grease.
