Hello boating friends:
I need to replace/rebuild my '94 Mariner 75hp lower unit. My old gear housing part # is 1667-9010-C3, and appears to be a long 13 spline drive shaft; however, I am getting alot of conflicting info on the web regarding G/H part numbers (1667-9011xx) and drive shaft splines (13, 14, 17) for my serial # (OD2843xx)! I can't even find any info on my existing G/H using the part #!!

Can anyone tell me what Lower Units will fit my motor? Any help is much appreciated!
