Hi, I bought a used 2001 GT and the wear ring was shot. I went through a company on ebay and bought a new one but found that the old one was really easy to remove because it didnt have to be cut out like my previous machines.The ring was snug but all that I had to do was pull it out by hand and then push the new one in by hand as well. The new ring didnt last the weekend so I bought one from my local dealer and again pulled the old one out by hand then put the new one in by hand. This wear ring only lasted the weekend again so I called a local fellow thats familiar with seadoos and he claims that some models will allow you to take the wear ring out easily espeacially those with the neopreme seal. After checking BRP there is no seal in the 2001 GT. My housing looks good but I really dont know if it could be warped but I doubt that it is. Is it possible that the BRP site could be listing the wrong wear ring for my machine. I did get a buddys housing with the brass fins but my machine wont even plane out with it on so I went back to my old housing.
