Impeller...when is 2" the same as 2.25"?

Pulled the RW pump this past w/e. Seems the JABSCO impeller needs replaced. In trying to source one, I find that they want tip-to-tip diameter. Well! I measure from tip-to-what's-left-of-tip and get near to 2 1/4 inches.
Do these things "grow", or is it a case of "close is enuff" when it comes to ultimate diameter? Seems ta be no 2 1/4" impellers listed.

I called the local (to home port) marina and found they had one 2"x7/8"X1/2" #1 (pin shaft) for only $46.93! Guess I'll hafta go in and hold one to the other and check. Once satisfied, I'll source via Amazon or elsewhere and get the spare.Since I'll need the one by the coming weekend; I'll justhafta bite the bullet and pay the price

TIA,
Paul

I believe that the 2" is the size of the cavity of the pump housing. The impeller measurement, from tip of the blade to tip of the opposite blade, should be slightly larger than the cavity in order for the blade to form a seal against the housing and the cam.

I suggest you go about this from a different angle. Gather the information about your pump, run it in Google with "replacement part" or "replacement impeller" and you should be directed to exactly the right size.
