This is a duplicate post but I didnt get more than one answer when I attached it to someone else's thread (sorry!) so I'm asking again:
can I ask the owners of Radice folders about vibration
I have a problem that if the boat is going forward at (say) 2knots and the engine is put into reverse, there is a lot of vibration (as if someone was using a percussion hammer on the hull) until I really rev the engine and get the prop fully open. Then its smooth.
Silette reckon that what's happening is that the prop is flapping ie opening to varying degrees as the wash from the boat going forward tries to close the prop and the engine revs try to open it - bit like a performing seal clapping its flippers together. Sounds feasible since the prop is well balanced and vibe free at other times. But it does worry me as Bowman used a grp stern tuibe when they built the boat so I'm nervous about damage.
Anyway, does your Radice do that? And do you have a P bracket or a shaft log?
