I ran the Redline Heavy for two 50 hour changes (B-1, 600hp)
No problems whatsover, and magnet had almost nothing on it.
Put m-1 75-90 in at last change because my Redline didn't show. Will look at magnet when changing here soon.
It does seem that I am seeing about 100rpm more with the M-1 when comparing the two. Could redline be that sticky?
The Redline takes forevvveeerr to drain and can be messy, but it seems to be the ultimate gearlube.
Always ran the M-1 gearlube in our racecars and no problem there either.

EASY WAY TO SOLVE THIS ISSUE CALL MERCURY RACING AND ASK THEM, simple physics roller bearings need a small amout of friction to turn and cone clutches need friction to grab not saying im 100% right but been building drives for 25 years and I wont use it.....it is a great lube in motors

Thanks for the input!

I use the Merc High Performance gear lube. I believe it is a pure synthetic, but can't swear to that. It goes in a Bravo 1. Engine is 500 hp ZZ502. Boat is a Wellcraft 23 Nova that weighs +,-4000 lbs. Heavy little sucker, not very efficient hull so it take some hp to get it moving fast. Does 70-73 depending on temp, humidity, chop. Mostly cruising but does get run hard from time to time.
Guess I'm a little nutty about changing the engine and out drive fluids, but I've never had a problem with either.

Was the "drive overheating drive resovoir overflowing" woth Redline Heavy Shock Proof Synthetic Gear Lube? If not what synthetic gear lube was it?
Thanks!

Thats if the bearing have flat spots which will cause the drive to overheat which will cause the bottle to overflow flat spot cause heat (heat causes expansion) bottle overflows

I understand.
What was the brand/make of synthetic gear lube in the drive when it experienced the over heat and the resulting over flow?

I have had good luck with Royal Purple. It may not be better, but from experience it doesnt seem to be any worse..
If you see any fuzz, that means the bearings are seeing it also.. Change it more often..

Thanks for the change interval rule of thumb.
What is Royal Purple?
What are your thoughts regarding issue of the drive "bearings flat spotting" because of the synthetics are too slick and as a result "the bearings are not rotating"?
What is your thoughts regarding the issue of the drive "fricton cone not working properly" because of the synthetics are too slick?

And they used to say thing about synthetic oil in motors with roller cams.
Not enough friction and the rollers don't turn....
I dunno, it's a crap shoot!
