Mercury Gear Lube R/R

[Fill Ess]

This past weekend I went to winterize my two small Merc outboards, and I used the same Quicksilver 90 Hi Perf gear lube that I always used in my Bravo IIIs.

These motors were both new this year and the lower units came pre-filled from the factory as delivered so I'm not sure exacly what it was from new.

When I drained the old gear lube, I couldn't get a good picture to focus and here it looks more like bubbles but in person it looked more like tiny metal flakes like you'd see in metallic paint:

Normal? Serious problem ?

Also for the first time I read the back of the bottle and it says to shake well. Does anyone shake well before using ???

Phil, with them being brand new, I wouldn't worry about it.

The stuff you're using is great stuff - it's a full synthetic and has benefits over the regular stuff (the regular stuff looks like motor oil color while this stuff is blue/green... which you know). It's not "required" for your engine like it is for Bravo's, but it certainly can't hurt. I see a few hundred motors a year at the shop and that's all we use (regardless of engine) with great results over many years.

Does the glitter stick to a magnet?

Something else you could try is to heat the oil up. Bubbles will quickly disappear.
