I took the pump to a local pool store that fixes/rebuilds motors and he suggested I send it back.

He said the noise wasn't normal and after running it dry, he tried to take off the propellor and just let the motor run to see if the noise continues.

Anyway, there was no luck in removing the propellor without using extreme force. This isn't normal, it should of came off fairly easy.

He decided to put it back together for me and said send it back. He didnt want to force it and break something that would cause the company to refuse sending me a new one.

Wish me luck, i've heard these online places aren't easy to deal with.
