Our cruise along the south coast has come to an end in Poole where the boat is moored awaiting haul out and repairs.
Back in Newlyn we had an incident where a bolt 'failed' in the prop to gearbox connection.
The prop thrashed about a bit until we realised what had happened and we were concerned that the shaft may have been bent.
When reconnected we tried to ascertain if the prop had, indeed , suffered.
At slow revs it did seem uneven but we were not sure if it had been like that before.
At about 1000 (engine) rpm it was hard to see any eccentricity, we tried to measure it with a screwdriver which though crude suggested that it was not out by more than around 3mm. We tried her out and there did not seem to be any vibration. We continued the trip checking all the time for vibration and overheating at the stern area.
All seemed well until we were leaving Poole where the cutlass bearing seems to have failed.
The local mechanic says the prop is 'horribly bent' by about 10mm but we thought that this was mainly due to the lack of the cutlass bearing ( it was far worse than what we had observed before the bearing went)
Reading up on the issue ( what we always do 'after the event'!) I understand that my shaft ( about 5 feet long and 1 1/2" diameter ) may 'sag' slightly at the centre until it is spinning at some revs.
Question is.... does it sound as if my shaft is really really bent beyond the limits at which it may be straightened. Fingers crossed.
