6100 is loud at 100%, is that normal?

I have a TS24 Dual 6100 kit and I just started them up last night and at 100% there is a very loud hum. I am sure it will be less noticeable once my main pumps fire up but was just curious if it is defective because I have had this same kit about a year ago and I don't remember it being so loud.

Thanks!

It can be normal when the pumps are new, air inside the motor and the need for some parts to wear in can cause this. It is a good idea when this happens to make sure the bush bearing is fully seated (collar around the prop well) and then install the drive unit under water to get the air out. Give it a couple weeks as well as the noise should go down.
