I have the b max drives that came with amsoil marine gear oil,called dean he did not recomend any name brand just aslong as synthetic . what do you use and where is the best place to buy it?
i have heard red line has a tendeacy to foam, imco recomends torco but dont see any dealers on web.

Amsoil RACE 75/90. ---- 2nd choice- Amsoil MARINE 75/90.

You should have asked Dean what he uses in his,Im sure he will say Mercrusier. This is my second boat with big power and the only thing that has been in them is Red Line,No problems as of yet, outside of a couple of top caps. By the way, as of now, I havent been able to save enough for B-maxs,I presently have Imcos but it works!!
Hope you the best in what-ever you use they are all good, just some better than others!! ( Like Females)

I use the Amsoil GL-4 Marine gear oil in my TRS drives....no problems.....Fred

RedLine Shock Proof Heavy in the TRS for 3yrs and still like new with little or no shavings.

AMSOIL Series 2000 Racing Gear Oil 75-90. It si 100% Synthetic and each time I change it, there is no silver color whatsoever! I HIGHLY reccommend it. You can become a dealer for like $20 per year and save some big money. Good luck.

Amsoil 75/90 Race series

AMSOIL GL-4 is great and so are the 75-90 weights. All the AMSOIL gear lubes seem to be perfect for outdrives.

I personally use GL-4. Change @ 50 hrs.

Amsoil 2000 75/90

DOES ANY BODY USE TORCO IN THEIR DRIVE? LOOKS LIKE MOST ARE USING THE AMSOIL.
