Hang on side powerhead, submersible?

[samwrang]

Are the "hang from the side" powerheads submersible? Aquaclear etc.

I have heard from a few people they can run submerged with no problems?

i wouldnt take their advice anymore. the intake holds the top of the impelller, i dont beleive the cord is protected on a filter that is supposed to be on the exterior of the tank. why would you want it in your tank anyway? just courious.

Powerhead or filter? reefnetworth's answer applies to filters, but the powerhead's certainly should be submersable - in my mind that's one of the things that makes a small pump a powerhead.
