Here in Australia with a similar ski and with 20 hrs more. Mine is broken at the moment following a drive shaft spline failure and in the process of repairing. Other wiser people on here may be able to provide more detailed guidance, however, there is an upgrade of the driveline available changing the carbon ring seal assembly from a screw type to the more reliable 'C' clip retained type. It is more about the driveshaft than the seal. The model has a history of failures and hence the modification (return back to 'c' clip shaft design). I believe Seadoo have also removed the old shaftso that any shaft replacement would be done with the modification. Worth asking if it has been done and if not having it done as part of a next service, because it fails without warning and can leave you (left me) stranded. Other than that it has gone fast enough, towed a tube and taken me fishing.
