Water pump issue

My water pump quit working so I got a new kit and when I pulled the foot, the housing looked like it had gotten got and melted a bit so I got a new housing also. All the vanes were gone of the pump. I got everything put back together and I still am not pumping water.
Is it possible that some shards from the impeller got pumped into the water jacket and clogged it?? I was going to pull the foot back off and try blowing air through the tell tale hole to see if anything came out.
Appreciate any ideas.
It is a 1999 Yamaha 40HP 2 stroke engine.

SeaRay,
you said all the vanes was gone on the old one ??? you might want to change the direction of vanes you have them now they might be reversed !!! just my thoughts on it !!! now another thing are you doing this with muffs ??? you might want to get a trash can or something you can fill up and try or take it the water !!!! muffs now of day don't work as good as they use to !!!

If all the vanes were gone I would bet on a clog someplace. They had to go somewhere.

I had it in a barrel of water. I am pretty sure some of the shards got up in the pipe. I'll start over. Probably changed 20 pumps over my lifetime (mine and friends) and never ran into this before, lucky I guess.

If the impeller gets torn up, vanes melted off, they went somewhere, maybe to the thermostat but I have found many times they wind up in the base, under the stainless steel plate that the impeller spins on, take it off, look in the base and the pickup below the impeller

Well they say discretion is the better part of valor, so I took my boat to my mechanic. He said he had never seen so much plastic and rubber in the cooling system. He had to pull the side engine cover and thermostat before he got all the pieces out. We guessed the plastic was some of the housing that got hot and chipped off. Was even some in the exhaust port.
All good now......I hope.
