Hello,

This is my first boat and I am attempting my first winterize. I followed the instructions in the various videos I watched online for changing the oil, stern drive oil and other things, but there is one thing I am unsure of. Whats the procedure for that bottle found in the picture below:

The Mercury Marine manual says it is the stern drive oil... I already drained and refilled the stern drive oil. Can I just dump this bottle and refill it? Can I just leave it as is? I was never really sure what this thing does. Thanks for your help.
