super maramu, vibrations generated when the engine is running


jlm@jlmertz.fr
 

Hello everyone
I have two friends who have a SM (1997 and 1999) who after having changed all the mountsĀ  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?
