For the record, my comments on lapping of the mating surface apply to the
kanzaki box that is typical with the Yanmar 20gm.
As to the question of adjustment - for sure verify the basics are within spec
first - oil, play in controls, etc. If however the adjustment is used to cheat
- like putting extra pressure on the mechanism- then obviously there is another
issue, and it Will eventually bite you. Came too close to that myself while
procrastinating on the gearbox repair....

I think you should try minor adjustments 1st. Then, if you need to open the
trany cover and move the shaft while in neutral and inspect the oil level.
I tested mine today after I rebuilt it and installed. A couple minor
adjusts in the reverse band nut and one small one to the forward. She
seems to run great and my reverse is now engaging when I hold it firm. I
had taken pics and saved all my notes and will share soon.
Good luck.
