Broken vanes in jet pump housing

[madhoosier853]

I have a 2002 seadoo rx di I'm currently replacing the wear ring on. This thing was in pretty bad shape when I started taking it apart, part of the wear ring actually came out as I was removing the impeller. Once I got my impeller out I noticed 2 of the "vanes" that direct water into the impeller have large chunks taken out, the rest look fine. My question is, how bad will this affect the overall performance of the pump and are they removable/replaceable without buying a whole new pump housing. I can't seem to find a way to get them out unless they are pressed in like the wear ring and need to be cut out. I don't know what to call the "vanes" so I haven't been able to find them in any searches when looking for parts.
