Wow, thank you very much for all the answers, you are all very helpful!!
I tried to move the engine
as descriped. But there is no movement.
I am now in a harbour which I will leave tomorrow. If we stay in a bay tomorrow for overnight, I will go diving
and see in which direction I can move the Prop/Shaft.
I will post the update then.
I am not very good in repairing this things, since I don't have the knowledge and the required tools. If I look the Video of replacing this bearing I will never be able to do that by myself. Maybe I have to hull
Actually I am in Spain
and in 2 Months I want to go over the Atlantic. Hopefully with less vibration... but if I am sailing, and put the reverse-gear, then the vibration of course stops.
By the way: I am not sure if it is important or not: But the worst vibrations I get, when I drive forward with about 4 knots and then have to stop immediately (for example in a harbour while maneuvering). So from neutral in Reverse and giving maybe 1400 RPM
while the boat still drives forward. Then the vibrations and the noise
are really awful...
So, you I will post again tomorrow or after-tomorrow... thanks again!!!
