Drive oil
 

Any opinions on drive oil other than mercury high perf for speedmasters out there?

:whistle:

Just like engine oil, a lot of opinions. Search and you will find many opinions.

Let me rephrase the question then, has anyone heard/experienced anything good or bad about amsoil?

I'll rephrase the answer, lots of comments about Amsoil, just search.

I run the Severe Gear along with many others.

I did do a search and I found a thread from over a year ago. A lot can happen in a year, new technology, new products, new opinions, etc. I was kinda looking for a bit more info than your "do a search" twice. Thanks for trying though.

My new boat has #5s so also curious what fluid to run.

I do believe that the Amsoil severe gear is better fluid then the amsoil marine gear oil. either 75/90 or 75/110 I doubt you can tell a difference in weight besides in your imagination.

I personally ran the Amsoil severe gear in our Imco SC drives but half of the decision was based on the great success I had running that fluid in the rear end of my cummins rams that haul over 25,000lbs daily with ZERO rear end failures between 5 trucks and over 2 million miles. The other reasons I like the Amsoil severe gear...easy to get in my area, buy in bulk in a 5 Gallon, use the same fluid as the trucks, write off on my business!

I personally believe that any good fluid will be fine and you will not notice a difference between one good sythentic fluid vs the other.

Many people rave over the Bravo Shops privately branded version of "neo" oil.

The fluid to watch right now is the NEW Mercury Racing outdrive gear lube that they now recommend in the #6 and M8 instead of the previous Torco http://www.mercuryracing.com/blog/vital-fluids/

Which drives do you have? lol Just kidding.

When it comes to the SSM III IV V drives, with guys running big power, I have heard amsoil severe gear is good stuff. I've also heard guys who have ran alot of power thru them, in extended offshore running, have had good results running 75w140 instead of 75w90.

I have never used NEO oil, but people rave about it. However, considering you need a 5 gallons to change the oil on a pair of SSM IV/V drives, I am not interested in spending almost 500 dollars on gear lube every spring.

This year I think I am going to try the Mobil Delvac full synthetic or Conoco Phillips full synthetic. The Conoco is approved by Eaton Roadranger, Rockwell Meritor, Dana axles for their 500K mile drain interval warranty. If its good for 500k miles in a semi truck differential and approved by those guys, I'll take my chances. Either one of those you can buy for around 160 bucks for a 5 gallon pail.

For the most part, I think oil "brand" is alot of marketing hype. Oils that cost 3 times as much as the next, rarely perform 3 times as good. I personally would rather use a name brand, decent priced, quality synthetic gear oil, and change it every spring, rather than run a real expensive specialty gear oil, and try and make it last 2 seasons. The SSM V is a very stout drive. Brand of oil IMO wont kill it. What will kill it, is lack of oil, or water contamination, or plane old abuse.

I ran Mobil Delvac 75 80 last season in my XR's with fantastic results. -Tried all the wonder lubes mentioned. Very impressed with Delvac.

I think thats what I am gonna use this year Kurt. I know you said you liked it. I've always been a fan of Mobil products too.

I could probably go buy 55 gallon drums of Fleet Lube at 5 bucks a quart, throw some cool color dye in it, maybe Blue dye, everyone likes Blue stuff. Then rebottle it in a fancy bottle, call it "EXTREME OFFSHORE RACING GEAR OIL", and sell the stuff for 15 bucks a quart in the oso classifieds, and retire at the age of 35.

Probably no worse than some of the other hyped up oils out there. Results can be surprising...

I think you're leaving money on the table Mild, I'll bet you could get $21 per quart!

Back when I was running my speedies I would change the oil every other week (cheep Dino gear lube) never had an Issue, I believe that proper Maintenance will save you $$ in the long run. I still change the gear oil twice a month on my bravos and they are going on 14 years without a brg failure, and they are seeing a very large amount of HP and a very high X. I have blown the floors out twice in that time on the clockwise drive. but that's not the lubes fault! I believe in PM and then some. The high priced lube is just that. So with that said I'm ready for the crap to fly!!
,

Joe i think like you. we used GM high performance full synthetic gear lube in some bravo drives with poor results. i was thinking well if GM did the research and runs the stuff in Z06 corvettes and diesel trucks its gotta work good for a bravo drive. Well after a couple drive failures the person rebuilding our drives asked what fluid we were using. i said the really expensive GM gear lube that i can get for free from work lol. he said thats the problem. the gm lube doesnt have any "tackifiers" in it and the gear lube runs right off the gears. so we switched to Quick silver high performance gear lube and didnt have a problem since. at first i was gonna declare B/S about the gm gear oil then i did my own test and sure as sh!t the quicksilver sticks to metal WAY better than the GM gear lube.

5"s on boxes and I were discussing what lube to use in our speedys. figured see what the speedmaster guys are using these days

I'm going to use the merc hi perf oil. If you buy it in a 16 gallon drum it's about $8 p/qt. and when you need 6 gallons for 1 boat...... 2 guys can split it or service a few other boats and sell it for the typical $14 p/qt

i get a kick out of guys that think some magical gear lube will stop shafts from twisting and gears from getting fatigued and breaking.some guys think a xr drive can take the abuse like a 6 drive if they use brand X lube.

I just used the Severe Gear 75w140 and it has a nice aroma. It has to be good.

Joking aside, I did just put it in. I also bought the Severe Gear 190 and I might even try it in a few weeks. It is a cool electric green color. If 140 is good, 190 has to be better right?

I use the Bravo Shop 75W90MRHD synthetic gear oil.

Running Mystic JT7 85W-140, Yes Mystic, in Mercury BlackHawks with 1:50 Gears attached to 550 Horse on each. Inexpensive enough to change a couple of times a season to check for any metals in the oil. Comes out a Pretty clear Red each time changed over the past few years. Was turned on to it by the late Brad Smith, SMITH POWER and will never change.

I have a friend who swears by the mystik gear lubes also. Readily avail and cheap at farm & fleet! So Brad liked the thicker oil? He was a sharp man and don't blame you for taking his advice .

Brad told me he had used it in a lot of the drives he and his dad worked on. There were some that would come back to them after two years of use and abuse, knowing the drivers, and the fluid would come out as red as it went in. Don't think he used it in the higher end #6's and so forth but would use what manf recommended there, after all you spend enough on a drive why would you skimp on the cost of oil (not saying Mystic is cheap but is Inexpensive and a Old Skool non marketed to death, putting money in the mans pocket product). For my BlackHawks it has been great. Brad rebuilt two of my drive upgrading gears and his dad just finished my spare (Bob "POP's" is a hell of a gear guy).

This is why I love this site. I am totally going to try that stuff. For that price I will change it weekly. And it would be worth it.

Anyone ever use gulf full synthetic 75w-90

This got me thinking as i need to fill both drives and will probably change the fluids in my Duramax also seeing how I'll be trailering this season. Just found a local shop that has the Mobil 75-80 in quarts for the normal $12 and 75-140 in 5 gal pail for $180. Do you think there would be an added benefit to running the 75-140 in this situation?

Not sure why anyone would be surprised by results using MYSTIC? Very high quality lubricant company. I use their greases exclusively. Thanks for sharing! Brad was a bright guy and left a void when he passed, however his legacy will live on forever and keep this sport we all cherish going strong for years to come.

Not busting your ballz, but just be careful using a 190wt. Channeling and other ill effects like resistance to flow in a given tolerance can actually increase wear. Heavier isn't always better. 140 shouldn't be a problem, but I wouldn't go any heavier. Up to you, but up to a point there is no gain.

I love the mystik greases. I use the Red grease for my truck grease jobs, and the green grease for my boat trailer. Plus the farm store near my lake house always has it crazy cheap! Like 1.89 a tube sometimes.

i use it on alot of vehicles but never in a boat..farm and fleet sells it for like 60 bux for a 5 gallon pail..

joe,,they make the oil in 15w50 also for your big truck.. http://www.farmandfleet.com/products...l#.U2gJ2oHk98E

I saw that. I was at the one in oswego last week, they had 15w40 diesel oil, on sale, 39.99 per 5 gallon bucket. Thats a great deal. If i get out there this week im gonna get me some.

yep Mystik motor oil and gear oil, been using in the shop for over 2 years now, not a problem and worth the price as so far.about 400 boats have it without any problems that I have changed. O'Reillys just had a 8 qt / jug on sale for 24.99 for the motor oil15 - 40. I think something of Citgo oil is in Mystik oil products. No 100 % sure but do I know merc motor oils are made by Citgo and the merc premium gear oil is made by Citgo as well.

I have been debating on switching oil myself especially since I just went from bravo drives at 2 1/2 quarts each to ssm3 drives which hold almost 3 gallons each would be nice to save some dough. Only thing that concerns me is I thought I read somewhere that "marine" gear lube has a special additive to displace water. True or false?

Yes they (marine gear oils) differ from automotive grade in that they contain extra water emulsifiers to disperse the water so it does not mix with the gear oil if contaminated. Most will tolerate about 10% contamination with water for very short periods of time.

for this is why I decided to stick with the Quicksilver HIPO from Walmart. $12 a qt isn't that bad and it has worked so far.

Be careful when switching to Mobil. On my 2.5/260 outie I thought I was doing it a favor bye running Mobil synthetic gear oil in it. Broke a prop shaft and when the drive was tore down to repair everthing was gelled up and looked terrible. I went back to using merc hi perf in it.

This also happened with my truck. When changing the front gear grease I ran short of dino (recomended) grease for the front end. I added mobile synthetic to the sqeeeze bottle with some of the dino oil and it also gelled.

Also whatever was used in for my drive oil was gelled in the bottom of the resivour at one time.

When switching from standard to synthetic I think it might be wise to run a test to see how they mix.

Am I the only one who has seen this?

I believe smitty (articfriends) ran amsoil severe gear with Lucas oil additive with good results after chewing p multiple upper sets. He said he was going to give neo a go and see how that did. Anyone ever hear his results???

I'm pretty sure marine gear oils are designed to mix with the water. You don't want seperation.....just like with water in engine oil and like with water in your fuel. Seperation is worse.

I'd like some oil with my water vs just water.

BTW: I did not look this up so I may be wrong. I have drained a ton of things with water - and those things that have let the water seperated have had much more issues - rusting/piting / seizing / no run etc.

Let the oil experts speak...lol.

Demulsify is what I implied

What does Ego have to do with anything ? You must have inserted emotion into my post in which in reality there was no emotion.

Do people attack you a lot ?

No. Your wrong. You taking emotion out of reading something that the typer had no emotion.

I said it from what I think is happening from my experience and without looking up what the experts say.

You need to calm down and stop thinking people (me in this case) are picking on you.

Only one person in this forum would I talk that way to, for a reason, and he has been banned...for those reasons.

Chill dude.

Other things in life to worry and stress out about.

This is not one of those.

I read back to see where you/I went wrong. I get it now. I quoted you.

My response was not towards you. I used your quote to show what I think.

The lol after the 'experts think' was not directed at you nor anyone else. It was a laugh at me because I could have been wrong with how I interpreted my experiences.

So...now I see what caused your reaction.

It was not towards you or anyone.

No emotion in it other than the giggle at myself.

Truce !
