Why is my fresh water pump squealing?

My engine is FWC, with the second pump run off the shaft on the front of the engine. I changed the impeller, which I do regularly, and put on a new belt, which I tightened carefully. Now I get this squealing noise anywhere above an idle. See the video.

Thoughts?

Only time this happened before was when the belt was worn and loose.

Belt...or bearing? Can you put the old belt back on to see if the problem goes away?

Is it possible the new belt is half an inch too long?

Did that. No change. Talk to me more about what the bearing might sound like.

Sounds like a bearing noise to me, the result of years of side loading and possible (I can't know for certain) over tightening.
