Water Impeller replacement not pumping water

[jamool24.7]

Hello

I replaced the water impeller in my yamaha 2002 8hp outboard however it not pumping water at the tell tail anymore. I have rebuilt the water pump twice with no luck. Is there anything worth checking for going to a dealer?

Thanks

Maybe a dumb question but did you make sure the water line was clear first?
