1990 Johnson/Evinrude V6 gearcase rebuild reassembly

This is not supposed to be a how-to and it does not cover every single step but hopefully it will help anyone who finds themselves staring blankly at the manual's occasionally vague and ambiguous steps or when the lab-like pictures in the manual didn't show quite what I would have liked to have seen. It's basically what I found myself looking for but unable to find while I was doing this.

The pictures are in order. Unfortunately I didn't take pictures of the disassembly. Maybe next time.

I don't intend to lead anyone in the wrong direction so if anyone sees something wrong or bad in these pictures please let me know and I'll edit.

Re: V6 gearcase reassembly pictures

You left out the most important part of the repair when replacing either the pinion and gears or the driveshaft and thrust bearings. The driveshaft has to be shimmed using the proper factory tool and the shims needed calculated from the measurements.

If you did not perform the shimming procedures and replaced the driveshaft and bearings, you may have serious gear problems in the near future.

Yes. I didn't actually end up rebuilding the one that broke the driveshaft because no shop would do just the shimming for me (they all said full rebuild cost, shaft shim or whole job, for more than the shimming tools :mad:), I ended up rebuilding another I had on hand which had sprung a leak at some point in the past. Covered in the thread that led up to this so I just pulled that pic down for the sake of clarity.
