I remember a discussion about misalignment on the impeller shaft and engine. Not that this one was difficult to figure but the degree is unbelievable. The ski came in for a carb rebuild. I'd say that saved the skis life. Initial inspection two broken motor mounts. After I got the ski running the rattle was unbelievable. Motor bracket bolts were loose also. She's spot on now. I keep telling people... you never know what you are buying. This particular ski the previous owner spent $1200 on a new impeller shaft install. Not sure what else he got but the jet pump never had a gasket either. I just gotta use my dial indicator. I'm so much faster with it and I can get the alignment much closer.... than needed of course but that's how I roll.
