We finished the last stretch of the Staffs and Worcs today, winding through narrow sandstone cuttings down to Stourport.
We’ll be staying with my brother and his wife for a few days. Meanwhile, here is a puzzle for you.
Our boat makes a screeching sound when the engine is going at about 1200 RPM. It starts at 1000 RPM and dies out around 1400 RPM. It happens when the engine is in forward or reverse, but not neutral. It does not happen when there is weed or grass clippings wrapped around the prop shaft. Other possible factors: there is a flexible coupling between the gearbox and the prop shaft, and according to the dipstick, the gearbox is overfilled with oil.
What is causing the screech, and what do we do to fix it (apart from keeping weed wrapped around the prop shaft)?
Hopefully we will find the answer soon, but any suggestions would be most welcome. In the mean time, there are rumors of a BBQ, so I’m signing off for now.
