1st let me say this is my 1st post😁

I have a 2003 Mercury/Tracker 90hp 2stroke, ser#OT699752. The bearing carrier tabs snapped and had to replace forward and pinion gear. Team mate bought a complete LU(same 2.31. gear ratio that came off a 2002 Mercury 90hp 2 stroke. Everything fits as it should(to the best of my knowledge) however, I can't get the bearing carrier to seat properly?? It sticks out maybe 1/8 or a little more??
1) is there any difference in parts from 2002-2003? I could find any and there were plenty of part#'s superseding #'s and comparable.
2) is it just the gears not lining up properly??

Any advice/correct information would be greatly appreciated!!

P.S Is their a specific torque for the threaded insearts and nuts? Can you just replace inserts with normal stainless bolts instead of the inserts? Thanks again!!
 
So you swapped parts out of the replacement gearcase? Why wouldn't you just bolt the replacement up and go? I'm sure I'm missing something here?
 
Welcome. Do you have any pictures? What does the reverse gear look like?
In order to add a picture, set up a file first for the reduced size, (under 1000k). I use litphoto.....creates your file immediately.
