Detecting gearbox damage with a stethoscope
A strange rattling noise when travelling under power? A diagnosis with medical equipment can help in some cases!

Owners usually know every sound on their boat. If a previously unfamiliar rattling noise is suddenly heard alongside the familiar engine noise, they become uneasy. Does the metallic sound indicate a worn bearing - or is it perhaps just badly stowed coffee cups? This was also the case for us: a strange clattering noise from the engine room, initially of mysterious origin, disturbed the peace when the engine was running.

A stethoscope can be used to locate the source. However, the diagnostic device should not be held directly against the machine, as the noise is far too loud. A wooden board can be used to dampen the noise. This is an excellent way of listening to the gearbox. Broken bearings, for example, can be recognised by crunching and rattling.

We have not yet found the source of the strange clacking noise in our case. However, we were able to rule out the gearbox and engine as the cause by examining them with a stethoscope.
