Thread: New noise......

  1. #1

    New noise......

    Probably nothing but as the title says... New noise you have to ask.

    1300 RPM, somewhat lively following seas. Intermittent hi then lo whine not horribly loud but noticeable... goes away, comes back. Audible in master state room and on aft deck. Nothing in engine rooms....

    Exhausts intermittently below water with resulting back pressure making music?

    The lively seas can induce a little movement of the shaft in the bearing creating a whine. Did it coincide with ramp? Or climbing a wave or surfing down a wave?

    The cadence was the same as the boat motion..... I like this answer.

    Exhaust underwater wouldn’t be a whine. Either cutlass bearings although I ve never had this happen on any boat or rudders? Does it happen under AP or someone steering ?

    Ride home this am into small chop. No noise. Panic alert cancelled.

    Pascal, I was wondering about hydraulic/stuffing box noises in the rudder.......
