The Yanmar 3gm30f on our BeneteauOceanis36cc makes unpleasant knocks when it is started which make make the shaft tremble and put some pressure on the shaft seal ( a VolvoBlack Jack).
The knocking stops when I give it more throttle.
The mechsnic says the motor needs to be raised a little in the front.
In order to do this the mountings in the front needs to be replaced.
I am uncertain if this is a nice or need to do repair.
The knocking can be avoided by giving throttle after the start or increasing the RPM in idle.
Views and tips on this is highly appreciated
