Is necessary to test and read.

No markings inside motors.
Conservative rule of thumb for motor power: 3watt/gram.

The weight of the motor and the Kv from a no load test will pretty much tell you all you need to know about a motor. And if you are working with a found/used motor the no load test will usually verify that it is in running condition.

If you don't have a watt meter yet you can use a DMM and run the motor up two times, measure the voltage on one and the current draw on the second and then Volts x Amps = Watts.

And you can get a DMM for free from Harbor Freight this week if you sign up to get their flyers by mail. They have a bunch of sales and flyers with free things on them, one current one is good for a free DMM!
