I think theres alot of drives out there that begin wearing the gear sets out, until they get thru the hardness of the surface, fatigue, and break.

While I do agree there's magical oil out there to stop drive failures, I still think a quality oil must be used. Otherwise, why don't we all just go to Autozone and buy the generic $3.99 a quart lube and go boating.

Bogey is somewhat correct. You can add some cushion with the oil, but you cannot take away forces.

I've broken many drives, and all where the result of torque loading...usually during planing.

I have had problems with my right hand (in cars, my right foot) doing what my brain tells it to do. LOL.

i agree that a good high quality lubricant is a must but my comment was more to point out the weakness of the bravo style drive.i have through the years been guilty of asking to much of the bravo style drive but i knew from the start that it was on borrowed time.i know that coolerman runs the neo in the 6 drives in his black thunder and it has big power,when he sais it is a good lubricant i am inclined to agree!

Yes force is force something has to give at some point.

Yeah I don't think its "magical" per se, more along the lines of better suited for said application. I absolutely agree that you need to run the best oil possible in a bravo. NEO is just one shining example of a product that's been validated in the field. There are others out there as you know. The stuff is pricey, but it beats the he** out of breaking a drive prematurely! Sometimes though metallurgy doesn't care about lube though, and stuff breaks. It's the gamble we all take.

I ran RED LINE in a drive I blew up.. it sat at the drives guys shop for a while and he said he`s never seen an oil stick to gears like that.. the stuff just didnt want to come off, hard to clean even.
I don`t know what that means but that was their ShockProof Gear oil.


You can still see it on the gear

I like you more every time I read another post, I sure wished I worked with more people like you

Does anyone with twins want to run two different oils in each drive and let us all know which is better? LOL
