Went to take a look under the nose cone the other day after swapping to a Solas prop earlier in the year an noticed the mercury 2-cones tease I had used was slightly darker in color. No water was visible anywhere so I was wondering if the slight discoloration was normal for some marine greases.

In stock form that grease is a Dijon mustard color and when I popped the cone off it was a light green olive color. Nothing look abnormal so that's why I was confused with the color change.
