Never had this problem but would fitting a PTFE sleeve the full length of the shaft tube help?  Bit like on a flexi shaft.

Hi Phil, Check if the shaft is straight by rolling it on a flat surface, if it is "true" noise is usually caused by out of line motor or worn universal joint.

When i built my Diva, the bearing at one end of the supplied prop had been attached at a slight angle so wouldn't even accept the shaft let alone turn. Maybe yours isn't as bad but is still slightly "off".

a picture of inside would help. there are reasons for noise, so we might be able to see it.
Is the coupling aligned, propshaft supported, motor mount flexible etc etc

Prop damage/balance?

I have had loud noise from models when the platform for the motor mounting has space between it and the hull. Really had bad noise on my smit neatherland model, I cured it by filling in the area under the bottom plywood shelf with P38.
