Jet pump

[555 ROD]

I have a 97 challenger 1800 , had a loud rumble noise out on the water,got back and when flushing engines one made a clanging sound. I checked and noticed the wear ring gone on the port side. I think my best and cheapest option is to get a good second hand pump, because i'm sure the impeller would be damaged as well. So with a new wear ring, bearings, seals, impeller etc it would be very expensive. I want to know if all the 140mm pumps are the same or only certain years, also the difference between the bronze and plastic ones. If anyone has a good pump and impeller that would fit i would be very interested. Iam in the UK but dont mind paying shipping,as there hard to find overhere. Many thanks, Rod.
