Driver lube higher weight to reduce shock

After consulting with the Amsoil rep, went with 75-90 Severe Gear, he reccomended it over the Marine, said it is a much better oil for this application. Said not to use the heavy stuff unless running real high HP, has better shock protection but doesnt "wash" the gears down as well.

Missed your post. I have never run it in drives. I have always used Merc lube with frequent changes and never had any issues.
I have run the Redline in hot rod car rear ends with great success. Launching of a starting line at 3500rpms with 12" slicks and shifts at 6000rpms and it worked well.
I think Mr G has a very good point about it being sticky and not letting the metal fall off the gears.

Talk to a friend of mine today about a guy running synthetic in his drive don't know the brand or weight, but it foamed and built so much pressure it blew all his drive lube into the bilge and when he removed his plug it shot out and they couldn't find it. This concerns me now.
Does anyone think the 75W110 will be too heavy and cause foaming issues? I've run the Amsoil 75w90 Marine lube, but never just plain gear lube...Don't know if there's a difference?

I just ran my boat today for the first time with the new 75w-110 in my bravo X's 30p. Ran flawlessly, and for the people who think you're going to lose speed do to being a touch heavier, my boat ran the same! I would not be concerned one bit. The most probable reason for the foaming would be water. Did he add anything to the product? That might cause an issue too.

Royal Purple is synthetic.. been running it for 15yrs or so.
If your buddy had water in the lube, it would have shown up on the drain.. At some point it will settle out.
RP has a very quick seperation period. Water falls out very quickly, so I have been told by the reps.
How did your buddy fill the drives?? That may or may not be an issue.
