4.430.212 was manufactured as a 912ULSFR-2 (fixed pitch prop)
-Optional overload clutch was installed.
You can get a -2 with or without the clutch so it is best to try a friction torque test to see if you have a clutch installed. If you lock the crank and cannot move the prop 30 degrees then you do not have an overload clutch.

Thank you, Rob.

Quick and precise, it's fine !
I'll do the test soon to confirm.

Sorry, this forum is for aircraft engines only. I suggest you make an enquiry on a Ski-Doo forum.
