I have a 95 spi and I started taking my jet pump apart to replace the wear ring when I noticed that 2 of the impeller housing fixed blade fins were half cracked off. The impeller is fine but after replacing the wear ring will this cause any significant problems because it is after the actual propulsion? I would assume not but please let me know what you guys think, I just want to order parts so I can get back on the water this weekend.
