Jet pump + Karcher

Finally got my karcher back off a mate! So today i took out the jet pump and got started cleaning it, by blasting the majority of the corrosion off it.
A before shot:

And after:


It looks like part of the jet pump needs welding to strengthen it a bit. I don't know what type of metal it is! Gal, Staino, or Alu, not sure. I'll give it to my bro-in-law to figure out.

Also the prop scrapes on the wear ring a bit. Quick fix: i'll grind it down just a little. This doesn't need to be perfect.
