I installed a new impeller yesterday. When I ran it after installation it pee'd good, however when I took it to water the next day it wasn't peeing anymore. Seems as if the impeller stopped running after one day. Any answers as to why? My motor is a Johnson 25hp 2 stroke.

Check the rubber tube, pull it from the block fitting....you might have a plug.

If it still doesn't pee, check for an overheat with an IR gun.

Next is pull the foot and examine everything related.

What did the old impeller look like? Any missing pieces that could have caused a blockage?

There is a chance. The last impeller was torn to shreds. There could've been leftover pieces I didn't clean out causing the issue.

sounds bad... you have to find any chunks .
Take down the LU and try a back flush check thermostat cavity fo r any bits .. try air blasting from the pee output . recheck the key

some cheap implellers have been known to slip on their center core and spin free ......with impeller fins going nowhere .

did you go oem or amazon ?

see trbl case on one ETEC impeller

Not just cheap ones....I spun my original 1991 evinrude 8 horse that I bought brand new.

Of course it was 25 years old at the time!
