Hello Bill and Chris,
hull # 167, 174, 202, and 210 have AUTOPROPS, first model with open stainless steel ball bearings. 146 and 156 have MAX-PROPS.
159 has a fixed prop. I think AMEL started with AUTOPROPS in 1996. However, at that time, some SMs still had a Maxprop (original), upon buyer's request (who didn't trust/like the cocker ears looking like strange prop!!).
I'm sure that hull 224 C-drive can bear an AUTOPROP.
I confirm the C-drive design has been modified in order to bear an AUTOPROP.
The first installed AUTOPROPS had open stainless steel bearings (for the blades).
The sealed bearings (steel balls) probably started in september 1999 with hull number around 275 (273 has it, 265 has open stainless steel bearings).
Have a good evening.
Thanks for the information. BTW, I got my information on the first SM 2000 from Amel.
I am absolutely positive that your hull 232 was not built in 2008. Did you accidentally make Satchimi 10 years younger? 😀
