Or do both and use the Marine Gear Lube which is a full synthetic and will protect your gears and your cone clutch.

At a race the Amsoil guy told be Severe Gear in the drive...can't win sometimes..


. would personally use Severe Gear in my Bravo. Either are good...what is Teague using these days?

I don't know the asnwer to what Teague uses. The Amsoil tech guys says he uses the Marine Gear Lube and the "People who have talked to Teague" says Severe gear. They are both good products.

What are the pros and cons of Redline Shock Proof gear lube in a Bravo drive?

I use Royal Purple gear lube. How does it compare to the others mentioned? About time to place an order again.

it's messy and stains, takes about 12 hours to drain and seemed to cost me about 100rpm, on the other hand it's an awesome gear lube.

I now prefer the M1 75/140, readily available and no apparent artificial coloring.

Here's a little fun reading for you.

I do not mind putting up with the messy nature (definately messy) and slow drain rate (I use a vacuum pump system) as long as it provides the best protection and does not cause performance problems elsewhere as in the clutch cone issue implied herein regarding other syn lubes.

Has anyone got any information or test results back on Mercury's new full 20-40 synthetic oil? I seen some on the shelf the other day at a Merc, service center. The only thing that concerned me about it, was the claims I read on the quart of oil. It said something to the effect of being formulated to protect the new catalyst systems ( emission) of there new engines. Isn't that the reason the new automotive engine oils don't protect as well because there lacking anti wear additives ( zinc) etc. because of damaging emission controls?

Got me wondering as well.
