OK, picked up the seal today. Looks perfect. It's ISP (International
Seal & Packing Co) www.intsealpack.com 1-800-651-2551

Part # R01220 Description: 16x28x7A NBR SEAL

You may not be able to order direct. I ordered thru a local pump
repair place. Just over $12 shipped. Seal was just over $4.

Will let everyone know how the pump goes back together.

Final post (I hope). I could not hammer the pulley onto the shaft,
even though I froze the pump for days and heated the pulley to 250
degrees. It would not go on. So I had to have it pressed on at a
boat repair place. They did it for free. Also needed a good puller
to take it off. Some folks may want to just find the seal and let the
mechanic do it. Pump is back together and ready to install.
