Sharing a finding and warning on jet pump drive failure at 110 hours of operation.
The impeller and driveshaft splines were found slipping due to spline wear. Cause of wear is due to separation of the impeller seal to the driveshaft. I found the same issue with my 2019 Seadoo GTR impeller seal at about the same hours of runtime. This is an easy proactive inspection to make.
Thank you Luc Lafreniere, for answering my questions initially on the similarity of these jet drives versus Seadoo!
In the YouTube link below, see the video I created below to explain what happened and how to disassemble.
