Is the Amsoil Marine recommended over the Severe Gear Oil?

good question, i have been wondering the same, ended up ordering the marine gear because it can handle some water contamination, the severe gear does not. would like some input from someone in the know.

Really depends on the application and HP in front of the drives. Put it this way, before the Marine Gear lube was ever available, the Severe Gear aka Series 2000 75w-90 was recommended, and used.

My take on the 10% water contamination is if it's leaking water in won't take long to be over 10% I'd rather have a gear lube that's going to withstand load,shock and temp I'm going with the 75w110

Maybe some Redline Heavy Shockproof

Have you tried this? Is it synthetic?

Anybody use the Redline stuff? Looks really interesting!

Ive used Redline oils in my modified cars.. I think it`s great stuff

Problem I see with Redline is, it is so sticky.. I am not sure it lets the metal drop out of suspension. Bravo's eat themselves and create a lot of metal. That metal dust needs to go away and the redline is so sticky.. I think it could fight the good effects of the product.
Just my .02

Interesting thought Dick...
Maybe that's why I never see any particles on my plugs

On the other hand, I have been using the Redline Heavy Duty Shock Proof since 2001 in my personal stuff and have also insisted on it on every power upgrade I have done for others. It has been outstanding. I'm sure the other high end lubes would deliver the same performance but I have just been comfortable with the Redline.
Sticky, Stinky and Messy is a true statement however...
