Where does my gear oil go?

[Relaxalot]

Help! Last time I was out I noticed the gear oil resevoir dropped about 1/2". Where does this oil go? Is this not good news? Every time I go out I notice a small amount gone 1/4" to 1/2". Any suggestions?

Most caps leak a little.
Any sheen in the water?

This happened on my last boat and is happening again on my new boat. Several mechanics have told me that the drive lubrication systems get air pockets in them and even though they don't leak it is normal to have to put drive oil in them. Don't know if this is true but it is what I have heard. Keep filling it up and if there are no leaks the air should eventually vent through the cap and you should not see it go down.

I don't see any leakage at all. No sheen in the water. Everything operates fine. I was just wondering, maybe it's air pockets?
Thanks,
