Good evening everybody I’ve been out messing with my 7.5 Chrysler and it runs like a champ, I drained the gear oil tonight after about 4 hours on the outboard since I last changed it to see how the seals are in the lower unit. The color was mostly dark green, the color of the oil I put into it but I there was some gray tenting to it and oil that sept out of the vent plug hole was completely light gray. I’m wondering if this is normal, means water is leaking into my lower unit, or if the gray is just the old gear oil I replaced (Which was extremely black) mixed with the new stuff?
