5643166 was produced 30-Sep-2003. Model 912 ULS2.

Other than that, the factory database has no additional information.
ULS2 does 'typically' get ordered configured with the slipper clutch, but it is an OPTIONAL part, so they don't always have it...

We have a produced a video which includes a procedure for checking whether or not your engine is equipped with the clutch, see https://www.rotax-owner.com/en/videos-topmenu/elearning-videos/60-friction-torque29

As an alternative are you able to confirm for a slipper clutch by serial number (P/N 887709 and S/N 25158)?

Sorry, I don't see anything there on those numbers. The database only tracks some of the larger sub-assemblies - not optional parts - and that data is only recorded for more recent engines
