Tried ebay and raymarine. the cups have fallen off and they do not supply these any longer, they will sell me a new set at £230? Only want the cups, even from an old unit or an upgrade!
I repeat, try a service agent or two. They usually have odds and ends lying around in their workshop, friend of mine got exactly what you want, for a few quid, from one of these agents.
I have the same problem with missing cups. I haven't retrieved the unit from the masthead yet but I did check for the availability of spares. Raymarine list a service kit on their website. Is this no longer available?
That looks just the job. i have been informed that these units suffer from seizing, therefore the shaft stops but the wind still tries to rotate the cups and eventually they come loose and fall off. Is it possible to replace the bearing or lubricate it?
