Gear Lube
 
What is the best possible gear lube for an Alpha 1 Gen 2. I know the Bravo's dont like it too slick due to clutch cone but the Alpha does not have that. Have 5500 lb 24 ft boat with a newer 357 magnum Plus series merc. Have been told its 300 hp. Just wanting to put in the best fluid I can.

Do you think this would be good in TRS drives as well?

I've always run the merc stuff!

In my 5s the merc stuff turns into water , super thin after a few weekends.
In my 6`s merc fluid expands and foams like crazy, thought there was something wrong with the drives but it was confirmed that is normal with the merc stuff.

Amsoil doesnt do any of that and I always had way less fuzz on the magnets .
Sorry but the merc stuff is junk

I agree the Merc HP green oil is junk. Their newest Merc Xtreme Performance Amber color oil is much better.

Simply use what the manufacturer spent $$$ billions on in R&D.
