Drive Unit Gear Ratio Identification All Bravo drive unit gear ratios are identified on each drive in two places: A) The first place to look is on the decal on the port side of the drive housing. It will have a number such as (1.50R) and then the seal number. B) The second place to look will be on the universal joint splined yoke. It will be identified with a letter such as (F). This method is explained in the following chart and is true for new or un-tampered with drive units. A drive unit could have had the gear ratio changed for high altitude, which would void out any application of the following chart. The gear ratio then would have to be determined by counting the teeth on the drive gear and the driven gear in the drive shaft housing and using the following chart for reference.
