My 2004 GTX 155 has just under 180 hours on it now. A couple of seasons ago I disassembled the pump and replaced all of the seals since it was never apart before and I wasn't sure about water intrusion. None was found and the bearing was in good shape, too. The wear ring and impeller looked good so I did not replace them.
Now that the next ski season is around the corner I removed the pump again figuring that it might be time to replace the wear ring / impeller, especially after 180 hours on the clock.
The SeaDoo manual specifies 0.014 inch max clearance between the impeller and wear ring. I've got between a line-to-line fit on one side to a maximum of 0.020 inch on the opposite. There is no runout of the shaft / bearing assembly so my guess is that the bore of the wear ring was not aligned when new. The groove in the wear ring is very shallow and does not have any chunks or grooves from debris in it.
My question is, is it even worth replacing the wear ring with this amount of radial clearance? Will I even notice it on the water? The impeller looks pretty good, just some minor nicks on the edges.
