Outdrive cause for concern?-gctid803706

[SaltyBones]

I changed the oil in my B3 outdrive for the first time. Pumped it in from the bottom till it came out the top vent hole, screwed that in and kept pumping till it came into the reservoir at the engine, and went to put the bottom screw in, but a good bit came out while I was getting that screw back in. Topped it off at the reservoir and took it out the past couple weekends.

Last weekend, I noticed the drive oil had dropped (maybe an hour total run time since the oil change). So, I topped it off again and ran it 20 more minutes. Opened the bottom screw on the drive once back to land and found these things coming out. The look metal and they are ridiculously thin. They don't look like metal on my finger and they don't stick to a magnet at all.

Any input on this would be much appreciated. I don't know if it's normal to have to watch the drive oil after an oil change, but the debris that came out concerned me.

The bottom screw is often magnetized to collect any small fragments. It is not uncommon to have a few on it.

The gear lube, chances are you had a air bubble that had to be worked out. Common when changing out your gear lube. Keep an eye on it in case any others work their way out. What gear lube did you use? On the B drive high performance is recommended (required).

Is this the wrong kind?

If so...Is it likely that I've caused a lot of damage w/an hour of runtime?

No damage yet,

That's an outboard lower oil 75 HP or lower...

Premium SAE 80W90 Gear Lube is recommended for lower units for outboards below 75 horsepower. Mercury Premium SAE 80W90 Gear Lube should not be mixed with Mercury High-Performance SAE 90 Gear Lube.

You most likely had Hi performance 90 to start with.

Drain & replace.

Those outdrives are more robust than people give them credit for. Ju.st change out the oil and keep an eye on things as usual.
