Have a gear lube drip on my port outdrive, boat is stored for the winter. There was no discoloration in the lube when we winterized. What could this be?

Possibly from when the lube was changed. Usually you'll get some that will run behind the carrier while R&R'ing the drain plug. Then over time with the drive down, it'll work it's way out.

Thanks for the reply. We did not change gear lube before winterization this year. It seems to be coming from where the lower portion of the Bravo is connected. It was quite cold but I do not believe it froze, does not get below 32 very often in the storage unit.
