Bobby, WHY ARE YOU SHOUTING?

JIM I'M NOT SHOUTING IT AS I TOLD YOU BEFORE FASTER FOR ME TO USE CAPS OR ALL SMALL AS I'M A VERY SLOW TYPER , ITS A PHYSICAL THING ,,SORRY ,I KNOW YOUR TRYING TO HELP !!

I'VE USED THE HEAVY SHOCH PROOF IN HIGH H.P. UNITS AND LIGHT IN A TON OF BRAVO'S WITH GREAT SUCSESS I WOULD ASK THEM WHICH IS EQUAL TO 75W90 WHICH IS WHAT BRAVO'S ECT. NEED
IT REALLY DOES WORK IN REAR ENDS AND GEAR BOXES AND DRIVES BETTER THAN ANYTHING I'VE TRIED ,,ITS WIDLY USED IN
NASCAR ECT.
JIM I DON'T THINK THERE IS A BETTER ENGINE OIL THAN AMSOIL,PERIOD
TO EACH HIS OWN ,THIS IS MY FINDINGS
HOPE IT HELPS
BOBBY

Ok, I understand. Like I said before, I am sure Redine is a great oil. I still am trying to figure out which Amsoil product to recommend since they have several different kinds. I know what Amsoil recommends and I know what Teague recommends, but that may not be the best one for extreme applications. I am convinced that Amsoil is not thinking of the Racing applications but merely the everyday boater. I am trying to find out what some of the Racers are using. Talisman racing and Wild Rose Racing are two offshore teams that are sponsored by Amsoil. I just need to get a hold of them.

Again, I am sure there is more than one great lube to use. Redline must work since a lot of teams use it. Amsoil and others must work too since a lot of other teams use them as well. I am not trying to promote one product over the other, just trying to find out some technical info.

Thanks,

NW_Jim.....Keep us updated on what you find out.

Will do.

HEY JIM I AGREE THEIR BOTH GREAT ,I'VE USED ALOT OF THEIR 2000 RACING OIL AND I FEEL ITS THE BEST MADE !
THE SHOCK PROOF REDLINE JUST WORKS WELL IN GEAR BOXES ECT. AND HAS SOOM GREAT PROPERTIES I'VE NOT FOUND ANYWHERE ELSE ,GOOD LUCK ON THE TECH ISSUE
BOBBY

I've used RedLine ShockProof Heavy for years without a single drive failure- it and Royal Purple are the only polyolester-based synthetic lubes available; the same base as the best turbine oils.

Jim- I find it interesting that Teague is recommending Amsoil lubes to you when they strongly recommended only RedLine ShockProof Heavy in their modified Bravos before (Powerboat article on companies modifying the Bravo drives, published last year.) Not that there is anything wrong with Amsoil- it is a definite improvement over the Merc lube, but does not have the same ability to 'wet' and stick to gears as the polyolester-based lubricants.

Please find out for us why/if they changed their minds, or if RedLine is still an acceptable lube to them (not that I'll change )
What is Imco recommending these days? They have a lot of modified drives out there now.

A quote from the Redline website:

"The Heavy can be rated as a 75W250 Gear Oil, but has the lower internal fluid friction of an SAE 75W90. The LightWeight can be rated as a 75W140 Gear Oil, but has the lower internal fluid friction of an SAE 30 motor oil. The SuperLight can be rated as a 70W90 Gear Oil, but has the lower internal fluid friction of an ATF. These ShockProofTM lubricants provide much greater viscosity in the thin layers between the gear teeth, but have very low internal fluid friction, which means very little power loss for the protection achieved. "

So, what weight would be best in a relatively stock (400-450hp) Bravo 1 application? I don't want to minimize weight at the expense of protection, but I don't want to put molasses in my drive either.

I'd like to know what "Properites" people are referring to. I know a lot of people run stuff just because they never had any failures. That does not mean it's because of the oil. Is anyone basing their decisions on stuff on paper like kinematic viscosity, foul ball wear test results etc. etc.? Just curious.

I guess I need to do some research on Redline and Royal Purple too.

This topic is of a lot of interest to me. I recently purchased a new boat with 500 EFI's and XR drives and want the best protection I can find for the drives and motors. I would also like to reduce the drag in the XR drives while not compromising their life. It seems the synthetics provide the best option and I have been leaning toward Red Line but want to do all the research........beyond what the manufacturer says.

Great thread
