3/4 hp motor, capacitor start.
This is the motor (cement mixer) that got under water for about 24 hours.
That was 4 months ago. I thought it would start and I simply had to clean
out the end-cap bearings. Won't start. Just hums.

Is there something obvious that I can do, or is the motor a goner? Should I
try to swap capacitors?

Thanks for all advice.

This is consistent with either bad caps, or non working centrifugal
switch. Both simple to test, but could be time consuming.

Try to measure voltage on the cap terminals when you start the
motor.

presuming motor spins unpowered properly, spin it up (rope pull will do) and
apply power while it's spinning - if it grabs and runs, then the starter
circuit is not working

Hum is good, means it isn't blowing the breaker.

I'd test the starter cap and look at the centrifugal switch. Water should not kill it.
I've washed a radar package before to deal with salt water contamination and after the
pieces dried, it worked fine.

The rope start suggestion to get quickly to will it run was excellent.

A bit of a safety precaution he make sure the rope doesn't get
grabbed by the shaft and pulled back in as it wraps up. Gets really
nasty on the fingers when that happens.
