Gear Lube-gctid802530

Yesterday while cleaning my lower unit, I noticed that some gear lube escaped.

The screw was loose.

I tightened it and checked the top screw and there was lube up to that level.

Do I need to add more or few lost CCs is ok?

If it is, as you say, a few cc's, you will probably spill more than that trying to add some back in. However, the challenge is how to confirm you only lost a few cc's without opening the vent screw. FIWM, I'd check it to confirm the level and add if it really needs it or change it out if the loose screw allowed water to be sucked in as the drive cooled after using it.

If the screw was not completely tightened then water could have been ingested into the unit. When is the last time you changed your gear lube? If not recently I would suggest draining and replacing anyway.

Is there a level monitor somewhere?

It was changed couple months ago, and only took it out few times

One time us all it takes to get water in it. You can try draining a bit to see what the condition is. If you get water or the oil is milky, change it. A bit of time and money now can save you thousands.

I agree, not worth the risk!

I'll spend $20 on new lube and buy myself a peace of mind

Be sure and replace the little rubber washers on both the vent plug and the lower plug. Get the proper washer, they're only $1. Without these washers the unit will leak/take on water.
