Another oil question
 

For those on the ragged edge of Bravo use... Neo, Alisyn, Amsoil, or Redline? Or, does it matter?

I have used Amsoil Severe Gear 75/110 for years, never had a failure in my Bravo1's,,,,,,yet.
After running 8 seasons I recently pulled both to freshen them, all internal parts look great,

Has anyone tried Torco RTF in an XR ?

Driven racing syn 75w -140

Amsoil Severe Gear works so well I am not going to jump around trying something different.

I used Amsoil Severe Gear for 1 season (2 oil changes per season). I started having trouble with a cone clutch slipping, almost immediately. I went back to Merc oil and after the first oil change, the cone clutch stopped slipping. Now, I'm sure the cone clutch was not in optimum condition - but in case someone has this problem, it might be that the oil is too slick. This problem only affected 1 drive, so I'm confident it was not the oil. I use Amsoil Dominator 15W-50 in engines and have for years.

Here's what i have done for 20 years.Never hurt a drive.
900hp blown Eliminator Daytona 27 Bravo XR,racing 1 hour wide open depending on conditions.6 races a year 3 years.
My avatar pic,632 cubers 850HP XR Bravo's Racing,3 years.Same drives but now with 525's.
Blown 502 maybe 520hp Stinger 222 wait for it, in front of a Alpha.Pleasure boat.Not a lot of use.
Fastlane 40 Bravo 1's.Blown unblown 454's,502,s.
I know there will be doubter's but i have never hurt a drive.
Merc HP oil with 3/4 litre of Lucas oil additive.That thick honey oil additive.Maybe cost's a bit of HP.
Also maybe i've just been lucky.Easy up and down.

Curious to know why owners are using the Amsoil Severe Gear, which is a land machine based product over Amsoil's Synthetic Marine Gear Lube?

Thats what im running, FWIW.

Need to order another case now that I think about it.

HOw long have you been running it and what's your opinions on its performance? Thanks

75/110 vs. 80/90 is my guess. More cushion for da pushin'.

Ive only ran it last season, as it was my first season with the new to me boat and it seems fine to me. I'm over powering my XR's with IMCO lowers by a good amount like everyone else and I don't expect it to help save me from that but I'm planning on running it again this year.

I also have the trick billet aluminum top caps from Max Machine Works on the uppers and have drive temp gauges as well. One drive had a stock finned cap when I bought it and it always ran 20* hotter than the drive with the billet cap on it....put a new billet cap on that one so they match and viola the drive temps are the same now.

NEO here. Same setup as above (Drive temp gauges, wags billet internally cooled caps, external showers), with addition of drive guardians.

I always thought Redline was the $hit, expensive and good, their marketing certainly makes it seem like a good choice.

I bought a 5 gallon bucket in 2015 of the heavy shockproof.

My drive guy says it has no shear strength which Redline vehemently disagrees with.

These lower gears were new 4 years ago.:
Have to be replaced because of wear and unable to shim them.
Surveyor says improper shimming, drive guy says wear and tear... who knows.

Plus the prop shaft sheared right off:

Chris where do you get the NEO stuff ?

This is interesting. My old style XR upper has a flat top cap. Not many are running drive temp gauges for real comparisons. Do you have drive showers? Is this cap an easy bolt on? BTW, I use the Mercury HP Gear Lube.

Bravo Shop carries NEO.

Good deal, should be just fine in all OE Bravo1's w/external showers behind 7.4 LX MPI Mercs Then.

Curious to know what goes into installing drive temp. Gauges?

I use the Merc Stuff. But I'm probably not on the ragged edge of Bravo use at 565HP....

Brad Penn 20-50 semi synthetic or VR1 20-50 full syn ??

In the drive??

NO, engines were being discussed also ?? maybe not...................Im running Shawn Penn in the drive...:D

There is a guy on here who is an Amsoil dealer that runs 10W40 Amsoil in his drives. Yes, drives. .

I knew that. VR1 for me too.

WTF? :bong:

I guess I'll join in on this. I just bought a 90 Cig cafe running some fairly fresh (rebuilt) IMCO Xtream Advantage SCs. The pervious owner has been running Cen-pe-co "Hi-Torque gear lube with temp tac" with good results for the last couple seasons 40-50hrs. He's a Farmer, motorsports enthusiest, drag races, races modifides, has a 90 mph 38 lightning with decent blower power and SSM 3 big shafts, a dry sump 1100hp/side strait bottom gun-w-6s, and he builds his own engines... Not that thats supposed to be some ringing endorcement for the lube but he does run it in some various equiptment and really likes it. Oil has always come out clean and particle/flake free. His dad generally drove the boat mostly, not a real heavy handed guy and not a lot of shock loading, easy up, easy down.. I've got a real vested interest in this topic and have been reading a
bit on the subject. I'm under no dilusion that things couldnt go snap/crackle/pop at any time with 750hp/28P Bravo
1s. I guess I have all kinds of concerns like others who dont run #6s lol..
Viscosity characteristics are interesting to me here in the North East where the sea water is blue lipps cold, are up to temp running temps are going to be comprable to quite a few guys here but maybe cooler than say Fla.. A lot of these conversations end up not being apples to apples..
Heres a link for the oil.http://www.cen-pe-co.com/Product%20D...rque%20Red.pdf
Now, I'm not sure I'm staying with this stuff or not and thats why I'm hear to learn, read some more and figure this all out....hopefully...

Engine oil shouldn't come out clean. If it comes out clean the detergent/dipersant package isn't doing it job.

Who was talking about engine oil?

lol. Oil threads ...

Did nt you post that gear oil brand on FB for a thread asking about gear oil or a gear all damaged up. Just asking

[QUOTE=BUP;4546213]Steve Smith posted some damage on a thread Mark Rinda started; I asked Mark who rebuild my drives and who I've talked to before, about his thoughts on me opening mine up and inspecting the pinion gear and clutch gear faces. I cant remember if I mentioned the gear oil before on FB, maybe but I couldnt find it in my comment history..

Sorry, misread the post.

Ken

I run Amsoil severe gear 75w110 with about a 1/3 quart of Lucas heavy duty oil stabilizer
