1999 GTX RFI jet pump

Does this impact the performance of the jet ski by a lot? I just noticed the broken piece when I was inspecting my jet pump.

Am I blind? I don't see anything broken.....

The part I circled in RED is the part that broke off. The one in GREEN is complete.

It’s pretty hard to see but if part of the straightener fin is gone then yes it’s a problem. It’s going to cause turbulence and cavitation to the water flowing off the impeller.
I would be surprised if whatever did the damage didn’t damage the impeller also.

Oddly enough, The impeller is actually perfect. Nothing wrong with it at all. I’ll just wait keep looking for a deal online and buy one when I see an opportunity.

The new plastic pumps often come in with chipped/broken vanes..(.the old brass pumps were almost indestructable),,,I like to go in with a dremel tool to round off any sharp edges,,,I find this helps.

Thank you. I’ll do that .

Usually the ski comes in for a torn wear ring,,,so they don't really know if their severe cavitation, or (lack of propulsion), is due to the wear ring, the chipped pump vanes, or a combination of both. So I replace the wear ring, and tel them to "try" it out,,,with them knowing that they may have to buy a new pump if they are still experiencing cavitation.
