It is exactly my conclusion bat the two fixed prop are perfect,
so I could not image it could be possible ...
Before to turn back to Autoprop (actually as spare) I will check
the big bolt on the bottom of the C-drive that fixed it on the
keel ...
Merci beaucoup for your help full answer ...

On my last boat I used to have a fixed three blade prop and there
was some vibration. It was a traditional shaft and stern tube
arrangement. I spent ages realigning the engine. Then I pulled the
shaft and sent it with the prop to a machine shop. The shaft was
true but the prop was not balanced properly. I decided to buy a
feathering prop and keep the old as a spare. No more
vibration....So it could be the prop.
I have two friends who have a SM (1997 and 1999) who
after having changed all the mounts and the coupling of
the engine have a significant residual vibration.
Both have the distinction of having a fixed three-blade
propeller.
Would there be in our group a person who had this
problem or could have a track?
