Will it harm a 24 volt motor to run it on 12 volts just to make sure
the brushes and everything are good? I know it will run slow but will
it have any harmful effects?

Not for a short test out of water - no.

If you mean to run the motor for a moment in air (no load) just to check
that it turns over then you won't hurt it. You may not learn much about
its condition either but if the motor runs smoothly on 12V then it is
probably OK.

Who knows what the speed control will do though.

Be careful about running any motor, trolling or otherwise, out of
water. If it is "momentary", you can probably get away with it.

The seals will heat up, and potentially burn out, without water.
Good luck,

....carry on.

Thanks everyone for your input. I didn't know about not running it out
of the water. Will be sure never to do that for more than a few
seconds.

I don't have experience with trolling motors, but I do have experience
with a variety of other electric motors. For example, the cheap speed
control for electric R/C boats is a resistor, dropping the voltage to
the motor to slow it down.

It seems to me that a 24V trolling motor will do just fine at 12V,
although only 1/2 as fast.
