Singing prop.....solved.
As you remember I complained about the noise my prop made....not a nice singy songy sound but something
reminiscent of a seized bearing...and loud too. The trick was to co-ordinate everything with the annual haulout.
So I teed it up with Glen at Porters that I would drop the prop in and he would do it on the spot (he did). Then I
had to get the shipwright to take it off as soon as the boat came out of the water so I could pick it up and run.
I wanted the prop off, fixed and back on so no extra time on the slip was needed.
It all went very smoothly.
Apparently the noise is made by the trailing edge of the prop and Glen machined a flat area 5or6mm wide
along the length of each blade to upset the flow off the edge. 'No guarantees' said Glen. Anyway with the haulout
complete and back in the water, it was time to try it. Success. Well worth the effort and extra cost for a much
quieter travel. The job was done at Bay View Marina and much thanks from me for the co-operation shown.
