Growling noise around cutlass , or maybe packing or ????
Hate to jump on the cutlass bandwagon, but..... I, too, just pulled the auxiliary (single cylinder, 12 HP dynamo, that shakes the teeth out of their sockets). After more money than I care to admit to, I stopped at replacing the cutlass bearing. Upon re-launch, the harmonic growl that increases with RPM spoiled the good sounds and exhaust of the rebuilt deisel!!
Two weeks later, out of the water and a cutlass change, end of growl!!
For and aft shaft movement is not as critical (especially with a rubber vibration damper in the shaft assembly) as ANY movement up/down or lateral in the cutlass.
Before the haul out expense, check the output shaft alignment with the prop shaft flange. After the re-power break-in period, some mis-alignment may have crept into the system via the motor mounts settling in.
