I've ran it in Bravo drives with good results.

RP is probably fine..it does seperate from water...we don't know if that is good or not?

But then again...who ever gets water in their drives?

I do the maintenance on a buddy's boat and use Amsoil in his Alpha drive. A couple of seasons ago he had a shift shaft seal leaking bad along with some other seals. He figured out he was getting water in the gear lube when he saw his gear lube monitor tank looked like carmel milkshake. He ran it for almost 30 hours this way. I drained the oil and it was a contaminated mess. The lube and water mixed together, they did not separate. A friend who is the Merc tech at a local marina tore down the drive and replaced all the seals. He said all the bearings and gears looked great. At the time, the drive had about 900 hours on it and that is the only work that had ever been done to it. Amsoil made a believer out of all of us after that incident. The drive has over 1,100 hours on it now and is still going strong as is the 5.0LX motor that runs Mobil 1 15W50.

I liked the Amsoil 2000 Marine drive oil; the new stuff looks thin; and the Amsoil reps said not to use it in offshore boats to use instead their Amsoil Severe Gear 75W-90 instead.

I would go with Severe Gear for offshore use personally if I were using Amsoil products.

Here is the new AMSOIL Severe Gear 75w-110. The gear oil rating have been split recently. The 90wt range was split in 2. The lower half remains a 90 (75w-90) and the upper half becomes a 110 (75w-110).

The 140 side has also been split. 190 is the new.

To my knowledge, Amsoil never made a 2000 series marine gear lube. There was Amsoil Series 2000 75W90 and there was a marine 80W90 lube. The Series 2000 was discontinued and replaced with Severe Gear 75W90. The old marine 80W90 was replaced with the newer marine 75/80W90 lube. The drive I referenced was running the older 80W90 marine lube, not the newest 75/80W90 lube. When I attended the Sunsation Rally a few years back, the Amsoil rep attending the show said not to run the new Severe Gear in outdrives (this was back when Series 2000 was being discontinued and used to be their suggested as well as Teague's suggested lube to run in Bravos) as it had too high of levels of sulfur in it and that it could attack the soft metals in the drive. Instead, he suggested using the 80W90 marine oil (75/80W90 marine lube was not out yet). So, sounds like it depends who you talk to at Amsoil as to what their suggested lube is for marine drives.

That's right in thinking way back..so what Amsoil product would you guys picks then?

Severe Gear for hard running frequent fluid changers.

Marine for cruisers that run all year on one drain. Marine is a better gear oil when contaminated with water I feel.

It is foolish to make a comment that the Severe Gear will harm a drive as it and the Marine are both GL-5.

Is this a new and improved oil filter from Mercury ?
