I have changed the gear lube religiously on my Merc 3.0 Alpha I outdrive. There are currently 250 hours on it.

There has never been any evidence of water in the oil. The boat is stored on a trailer and launched for each use.

The mystery is that I have to occasionally add lube to the reservoir. There is never any puddling of lube on the driveway or any visible leakage of any kind. I see no evidence of lube in the transom.

Where in the world is it going?

It could be it only leak while it turning and hot. pull the drive and drain the gear lube and do a pressure check. ALso check the bellows area for gear lube.
