So you can use it where 75W-90 or 80W-90 and GL-4 or GL-5 is recommended. This is a synthetic marine gear lube manufactured and tested specifically for marine applications and not just an automotive gear lube. Most sterndrives require GL-5 performance specification. This means that any GL-5 gear lube must contain Extreme Pressure additives (sulfur phosphorus). The trick is to formulate these additives to perform where possible water contamination can occur, such as below the water line in sterndrives. The AMSOIL AGM does not loose any extreme pressure performance even when subjected to 10% water contamination. It also does not foam when subjected to 10% water contamination. This means that is provides full film protection for high performance boats even when subjected to shock loading that can be caused by cavitation and without foaming or loosing any extreme pressure protection.
Most of this information can be found on AMSOIL.com web page under Product information – Gear Lubes and Chain case lubricants – AGM Universal Synthetic Gear Lube SAE 75W/80W-90 .
The web page also addresses the shock loading affect that cavitation from heavily loaded engines can cause. It seems that the extreme pressure protection built into the new AGM marine gear lube is about 50% greater than conventional gear lubes.
I know that the Series 2000 gear lube was very much liked, however the new AGM has more testing in regards to marine environment than the Series 2000 ever did. The oil that replaced the Series 2000 is called Severe Gear and is a 75W-90 Synthetic gear lube. It was designed for severe service in differential applications under extreme load and high temperatures such as the tow vehicles you use to tow your boats. Yes it can be used in your sterndrives with confidence also.
I hope this helps the members to understand more about the new AMSOIL Synthetic Marine Gear Lube.

Welcome to the board Kevin and thanks for the Info .
I had already ordered it I just received the AGM1 last week
.I was wanting it the gallon containers like the old stuff. But they didn't offer it .I bought 2 cases 24 qts and it laid in a $6.00 per quart.2 cases was 49.60lbs 
Also Imco told me they recommend the Torco oil for there drives .
Dean at the Bravo shop recommends for my B Max drives the Amsoil.
DrNautica .I tried the Alisyn Pro Gear 2 in my Bravo drive . Iw was on my old 28 Scarab with 828hp. I ran it for 2 days . You could tell a difference just by spinning the prop by hand .You could spin it and it would spin for awhile . Made me believe it was very thin oil
. The next day i ran the boat and it foamed real bad. I drained out the Alisyn Pro Gear 2 lube and put back the Merc green stuff . No foaming.Thats was my experience with it . I figured it was not worth taking a chance . My buddy's that drag race the outboard stuff are still using it . But there running the Motec computers and dash so there looking for every little thing that will give them an advantage at no mater what the cost Like Hydro says it boils down to personal preference . I don't think we will every see unbiased test between them Kinda like Fountain and Outerlimits will not do a apples to apples test same power and weight?
Thats my 2 dollars worth

Re: Amsoil's New Gear Lube
We know we have feedback from many users that Royal Purple; Amsoil; Mobil-1 and Torco (since it's in #6's) dosen't foam.
That narrows things down a bit if switching from Merc HP.
I feel comfortable using any of these fine products.

I guess it usually goes..oil...lube...grease. Just viscosity terms I suppose.

Re: Amsoil's New Gear Lube
Oops, I meant with all the discussion of these oils, where does the Merc green stuff fit in? I thought it was synthetic.
I have only run the green Merc stuff in my Bravo, and have had no trouble, but I only have a micro boat with some reasonable power....

I ran Merc green for 10 years. Then experimented and tried RP and Mobil-1. I never had a problem with Merc green and thought the synthetics ran very well. I know that synthetics can take more heat and resist shear better...the prop spins more freely...so I switched.
Mercury green is a very good product...so i didn;t see any earth shattering difference quite frankly.
I feel much stronger about using a PAO synthetic in an engine however.

However since GL-6 is obsolete {no longer used by the American Petroleum Institute, (API)}, and the test equipment and procedures are not used any longer by labs, nobody knows for sure if they actually meet the obsolete GL-6 test requirements. This is the reason AMSOIL prefers to use the highest API GL rating in use today, GL-5 and not use speculated API performance standards such as API GL-6.

One of the biggest causes of drive failure is when the seals blow and lots of water gets into the unit. It would be great if a device could be made to detect water in a drive quickly and set off an alarm and shut down immediately. I would buy a couple of those!

It signifies that the product exceeds current GL-5 mandates.
It has some significance in that respect.
Mobil-1... Gearlube container's read GL-5+
Torco... GL-6
Redline... GL-6
...ok so ya got me going 30 mph in a 25 mph zone...
What we don't know for sure is what Mercury Green is rated at because it is not on the container and the techs there could not tell me. I am guessing it is between a GL-4 and not quite a GL-5.
Now Troutly...get back to modeling your Apache' swim trunks....
