The parts motor I have in the shop was a coarse splined TN-26. Sorry to keep you waiting.
If you have a bad shaft with good splines, the end can be cut off and grafted to a good shaft with bad splines. I’ve done this fix on quite a few motors with good results. When it warms up a bit, the ’69 Merc 200 will be the next one getting this treatment done to it. Watch for it!
And another one.
