If the options were that cut'n'dried, I'd replace the impeller too...
but why stop there? Ignition failure due to rotted insulation is at
least as likely to leave one stranded.

Stop trying to semantic your way out of this, you are a poor debator. An
ignition stranding can be easily fixed, a powerhead failure is a
"catastrophic failure" type stranding.

Just because you had good luck with 100 inpellers and the one you had to
change was a bitch and 1/2, does not make you right - it makes you biased.
Your position is wrong, but it's yours based on personal experience. The
*collective* experience dictates the right answer.
