I found that the amsoil synthetic combined with cryo treating/proper gear surface prep seems to give the best life of the gears under extreme hp situations. I tested alot of gears with royal purple and after switching to amsoil have realized it works better. Merc hp is fine for stock boats but I had no luck with gears using it,Smitty
Are you using isotropic micropolishing on the gear sets? If so, have you tried the REM process?

Smitty,
Who does the treatments in our area (NJ)? I have one of my lowers apart with about 20 hours on new gears so I figure it would be a great time to get the treatment done since the gears have taken a "set".
I also use the Amsoil gear lube. Are you using the marine lube or the severe gear?

I don't know who does the gears in the Jersey area but there are many places thru-out USA.I have a shop that I work exclusively with that does my gear treatments,it's a multi step process,we have experimented with different treatments and processes to try to find the most durability. I'm using the severe gear Amsoil,I'm very happy with it. You can pm me if interested in getting gears done,Smitty

I'm using cryo'ed gears and Royal Purple 75W90 and oil cooler, filter and circulation pump (From Mr Gadgets/Dick)). Still during break in with 6.5 hours.
Replaced the filter after 4.5 hours and there was pretty much debris in it and that was from 0-4000rpm with no boost. I will change the filter after another 1-2 hours since I'm putting on some boost now.
The cooler and filter seems to works very good! :seeya:

Smitty, sorry for the confusion, I didn't look at your location and assumed you were Smitty from OPA, NJ.
Regardless, thanks for the info.

Synthetics = twice the cost, half as good.
We went out and made some of our own. My brother did the logo, look for the W. It is a mineral base with one additive.
If you are running a wet-sump... High temp type oil (green or yellow).
If you are running a merc dry-sump (ie fake drysump).... see above.
If you are running a weismann dry-sump...... mineral base 30 wt gl5/gl6
pick your poison.

I run the HP Merc stuff in my Imco. No problems yet.
I would have thought more guys would be using Merc stuff.
