If the top cap is removed U can tell by what kind of gears found

All Merc Bravo style drives take about 3 quarts of gear lube.
Its a swept back upper with Imco steering back cap and it also has the finned top cap that XR's have.
Most likely an XR upper, but you would need to pull the top cap or back cap to verify what gears it has.

Thanks. I will see if i take of the top cap. But it is more like a XR then X. If I look at a old picture of the Bravo drive, I think I can see a XR decal at the back cap, but im not sure.

Thank you!
Yes it is more like a XR upper with the finned top cap.

If I pull the top cap or back cap, do I need to replace any o-rings or sealant if I want to check the gears?

And my second question. I have drained the gear oil and about to order new oil.
Wich gear oil should I use and how do I identify wich gear oil it was in the drive?
The gear oil in the drive and gear oil in the reservoir is blue/green color.

Should I use the same oil that was in the drive, or can I order the Mercury Racing gear oil SAE 85W-90?

When I search for the SAE 85W-90 oil, it looks like the color is the same as the oil in my drive. Blue/green color.

Many use different lubes but suggest just using Merc 85w-90 Green stuff

Removing the rear cap will not normally need a new o-ring, but if tis damaged then it will need it. The upper cap shows signs of pitting. My thought about the rear cap was because the top showed pitting, so concern if rear also has same. Can also see if there has been lube leaking into shift area. If it was then would also see lube on shift fork

Do you want to send me a link to the specific gear lube you mean? When I mentioned the 85w-90 I meant this one. It says dont mix with other brands/gear oils.. But I cant tell wich one I have today



Okey, so you mean its better to remove the rear cap to identify two ”problem areas” at the same time?

The bluish green gear lube is Merc(Quicksilver) High Performance Gear lube.

The pic you posted is the new Merc Racing Gear Oil which is supposed to be even better than the Merc (Quicksilver) High Performance.

The top cap and back cap O ring seals will most likely be fine to reuse. I would just pull the back cap.

Thank you Griff! I just pull the back cap then.

Is it OK to mix the Merc Racing gear oil with the Quicksilver oil?
Or should I drain all the oil before I buy and fill it with the Merc Racing oil?

I think like this, as long as the both oil is syntetich, the Merc quicksilver is 75w-90 and the Merc Racing is 85w-90, it is good to go?

Mixing is for the most part is in regard to having one kind of lube in and adding another to fill. Your drained, so use only one kind
