Whatever the "last" number is, isn't really a significance issue as running any number combination, they all come up as an MERCRUISER - (BRAVO 1 Drive (1996)
Service Literature for MERCRUISER BI-ROTATION BRAVO 1. 1.50:1 gear ratio when manufactured new.

I will add that if your serial # is unreadable and your drive ratio stamp marking is gone here is the tip. Pull your drive an a letter will or should be stamped on your universal joint splined yoke. This is for new - or used drives that have been unchanged and or untampered. The letter means what your gear ratio is. for example listed below and I will post bravo I and later post alpha, Bravo II and Bravo III.
BRAVO I
C = 1.65:1
F = 1.50:1
H = 1.36:1

Continuing from post 7.
Bravo III both gas and diesel apps
H = 1.36.1
F = 1.50.1
C = 1.65.1
G = 1.81.1
B = 2.00.1
K = 2.20.1
N = 2.43.1
Read post 7 for explanation. do not feel like typing it all over again.
