Gear Lubes
There are two types of drive lube. Premium and High Performance.
Older drives, such as the ones listed below use Mercruiser Premium Gear Lube.
R, MR, Alpha One, II, IITR, TR, TRS All used Premium although they can also use Mercruiser High Performance Gear Lube. The Mercruiser Premium Gear Lube looks translucent caramel in color.
Bravo One, Bravo Two and Bravo III's all MUST use High Performance Gear Lube. Alpha One Gen II drives also use High Performance Gear Lube.
High Performance Gear Lube has a Blueish-Green green color. It is specially formulated to work well with the Bravo style cone clutch system.
Drive Lube Capacity
You will always use more lube than the factory specified capacity.
R, MR, Alpha One and Alpha One Gen II's all use about one quart.
Bravo Ones use about 3 quarts and a Bravo II or Bravo III will use a little over 3 quarts.
A TRS will use 1 Gallon.
Always buy a little more in case you spill some or need to top off a reservoir.
