Here a drive, there a drive, every where I break a drive.

I run merc hp. If I switched I would probably use Mobil 1. Most of the specialty oils are made from mobil 1 base stock, then add their own additives. Amsoil does I think, and probably Royal Purple also. Basically I think they are all high quality and you probably can't go wrong with any of them. Its like choosing between Lambo or Ferrari. I prefer a lambo, but not because it's better, I just like it.

Amsoil has been around decades before Mobil 1. Plus theres many other products they cover.
I tested side by side comparisons. 6000 rpms 1200 hp, amsoil in the port engine and moblie 1 in the starboard,26 degree differance between the two. Swaped oils from one port to starboard and the differance
followed. I was hoping they would hold the same temp its alot cheaper when your not paying shipping and can purchase moblil 1 from any autostore. I run Amsoil in the engines,drives,transmissions,power steering and trim pumps.
Also Amsoil makes many different levels of synthetic oils at the same weight.Big money difference!!

I'd run redline if I had it and used to, just ran out and realized I could do an oil change in 15 minutes with M-1 versus waiting overnight for the shockproof to drain:D

I run royal purple for years , Other than just plain breaking a shat or housing the drive gears and bearings looked good. But the oil allways smeld burnt. I run verry hard !! I change my drive oil every other oil change. There is no filter in a bravo. so I beleve the more you chang it the bet. I have put 260 hrs on one pair of drives with 500 efis in front of them. But still dont like that burnt smell.

It probably has that burnt smell because it really is getting too HOT! Therefore, that should actually tell you your drives aren't really getting the protection that they deserve. Heat obviously means friction, and we all know where the friction is generated.
