Ok, I have the out drive removed from my 89 OMC cobra to change the gears, bearings and seals in the upper gear case. Can I just use the same shims for the gears (bearing carrier)when I am putting them back together or will I have to remeasure. If the gears and bearing are the same as the originals nothing should change, right? And if so is there a way to take these measurements before I pull the gear case compleatly apart.

Wrong. Gears are machined to matched sets. and must be reshimmed using the proper special tools to get the job done so it will last longer than a few trips.
