Has anyone fitted Kort nozzles?
The risk of getting a rope around my prop and shaft has caused me to consider fitting a guard. As well as reducing that risk, I may get a slight improvement in performance under power, as Kort nozzles increase thrust. There should be less vibration caused by the small gap between the end of the blades and the hull, and there might be a reduction in, or even elimination of, prop walk when going astern, which would be nice. But if this happens, it will be harder to turn sharply by going ahead then astern in bursts.
Have any of your readers have tried this? Is there a flaw in my reasoning? John Pennefather, Sydney
