Is Mercury High Performance Gear Lube + the top of the line for Merc? Is that a synthetic or is it a mineral based oil? What is the viscosity? I have heard this is a private labeled Amsoil synthetic. Has anyone else heard this? Just curious.

I use RedLine ShockProof Heavy in my Alphas on the Formula- I have Simrek drive showers and drive reservoirs as well. Never had a problem with them (twin SBC's). Although pricey, I think it's the best lube you can put in an Alpha drive- they run very warm!

Only one problem I see here is that Mobil 1 has a GL - 5 rating and from what I have been told outdrives require a GL - 4 rating. The differance between the two is GL -5 has additives that damage brass and bronze. Good for rear axles but not for transmissions. Coastal is the only one I have found that states it is good for GL - 3, 4 and 5.
