Ello to all,
My Beneteau cyclades 39.3 makes a shaft noising when under noising, how more rpms, more the noise.
The engine its aligned, the noise its not from the engine, it comes from the shaft propeller in the junction from the hull to the shaft.
Any one with the same problem?
Thank you very much.

A loose zinc, old cutless bearing, bent shaft, electrolysis on the stern tube, a nick in the prop, lots of things it could be
