Hi everyone, this came up in my survey when I bought the boat but there is a slight vibration on the starboard engine. It doesn't happen in neutral, only in gear, and its significance changes based on rpm. We don't feel any vibrations in the boat except for in certain sea states such as a decent following sea. Maybe the props are loaded a different way when they are pushing water backwards and a following sea applies pressure forward. Not sure if this is normal behavior or if it is related to what you see in this video and just magnified.
In any case, since the engine is smooth as silk in neutral I assume this is either a shaft or prop issue.
If you don't mind taking a look at the video and letting me know what you think, that would be great. In the video you can see the engine shake a little bit, and you can see an oscillating movement at the shaft seal.
