I purchased a non running Kawi 900ZXi, the unit shook like crazy once running. I checked over the entire unit to find the impeller missing 3/8" of its outer diameter. I ordered the new Solas impeller from I Boats not knowing how much of the housing was worn or missing. I slipped the impeller into the bore and I was supprised that I had less than 0.010" clearance with the housing. Awesome, she goes into the lake this weekend, Let the good times roll again. Fit and finish is top notch, a great fitting replacement, price was great also.
