Hope you have better luck than I did. Both my original merc pumps leaked at the shaft. One damaged the belt because the shaft slid out. Replaced them with Sierra pumps and both of them leaked.
 
I don't know. Everything was installed by a professional tech. I doubt that the belt was so tight it ruined the lip seal. It didn't leak for a few years.
