When refilling its best to refill by pumping fluid into the bottom oil plug until it comes out the top plug. This method assures all the air in the drive gets displaced with the gear oil.
You also don’t want to let the drive sit around too long with out oil in it since leaving the parts exposed to air could cause the internals to rust. So if you don’t intend to get it pressure tested for a while I’d get some fluid back in it.
Good luck.

As Gerry said, it could be the prop shaft seal, but often its the shift rod seal.. Some motors us a mild steel shaft[ as opposed to stainless steel] for some reason, and they get rusty and crusty, and tear the tiny shift rod seal up, and allow water in.. The only way you will know for sure is to drop the lower unit.. You can try the prop shaft seal first.. Remove the prop, and check for fishing line tangled around the shaft.. You might get lucky and just have to replace the prop seal... Really the best way to do it is have the unit pressure tested and resealed.. Unfortunately, lower unit seals aren't cheap and are VERY easy to destroy if you don't have the right tools to do the job.. Even if you're good with a wrench, you need to research your particular motor to see if its a do it yourselfer friendly design..,, some are really tough to reseal without the factory removers/installers... bob
