When you say bearing runout, what are you talking about? Wobble at the crank due to worn bearings? I recently acquired a couple of 18-20-25 powerheads from a closed marina and noticed excessive play in the crank. This winter I’ll split the crankcase and see if there is a broken crank or worn out bearing in either of them (pretty sure one is broken, and the other is worn).

Unfortunately, sloppy upper bearing/crankshafts were not uncommon for these engines. And, unfortunately, they came from the factory this way. I’m guessing OMC let the tolerances slip on these parts. I just don’t want you pulling the powerheads apart only to find nothing really "wrong". I guess what I’m saying is don’t bother to pull these things apart unless the slop is really excessive and obvious wear due to rust is found.
