quote Dan in TN:
I believe the #378330 rod (replacement) that takes the wrist pin bearings & other parts mentioned will go all the way back to the QD-10. I have collected up several sets of this stuff. I have two motors to rebuild. One with broken crank because PO didn’t know how to remove flywheel. $15 motor. Said it ran fine, but needed coils? Upon tear down like FrankR said the piston wrist pin holes were shot!
The nice thing about this repair is I believe it will allow the motor to be run on a leaner fuel/oil mix. Might not go all the way to 50/1, but 32/1 or even 40/1 would clean things up nicely. Not too worried about the center main as later model engines were at 50/1 with that setup. JMHO

Dan, are you saying that pistons and rods from the Johnson QD 10 hp series
are interchangeable with the subject motor? I tried looking up parts numbers
between the two motors last night, (QD-14 & 1959 Evinrude 10 hp) and the only numbers that matched
up were the piston rings, but I’m not up on superseding numbers, etc.
I have a "froze up" QD-10, but probably not any good no how.
Has anyone ever fixed the wrist pin slop on these by using over sized wrist pins?
Thanks!
Prepare to be boarded!
