Thanks Jim, Great idea. I am going to change the impeller Friday. I have
watched the video as well. Perfect!

A couple of comments on the impeller change.  Even if you aren't changing
the belts, it's far easier to remove the pump and turn it around like shown
in the video. I tried not to do that the first time I changed it and it was
a bear and took twice as long. Another trick is to put a zip tie around the
new impeller blades and tighten it until the blades are deformed in the
direction of the old impeller and then slip it off as you push the impeller
home. Nice video. Filmed on Oriental NC where we keep our boat.
