Re: super maramu, vibrations generated when the engine is running

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.

Hello everyone
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?
