Are these two drives interchangeable? Any advantages of one over the other ? Thanks

The B-II is a tug boat drive, it swings a Monster prop, like for houseboats, 'n barges,..... Goin' from a B-I to a B-III is usually a Good move on most hulls,....

But depending on the years of the drives you have to be careful of the oil passage hole between the upper and lower units as the earlier years didn't have an oil passage like the later models did. BRAVO DRIVE UNIT/HOUSING COMPARISON AND IDENTIFICATION DRIVE UNIT GEAR RATIO IDENTIFICATION Also you have to know the gear ratios between the two drives because the lower has different gear tooth counts. http://www.mercruiserparts.com/Show_...%28BRAVO+II%29 -1641-8294A19GEAR HOUSING ASSEMBLY (1.50:1 - 1.65:1 Ratio) $4,350.00$3,896.081 -1641-8294A16GEAR HOUSING ASSEMBLY (1.81:1 - 2.00:1 - 2.20:1 Ratio) $4,350.00$3,896.081
