Re: [Amel Yacht Owners] Genoa electric furling gears



The trick may be to locate someone with a computerised gear cutting equipment. We needed to use two people…… who had a machine to resurface the worm drive (400 km away in Christchurch)  the second in our town to make a new gear. The other key issue was to find a piece of suitable alloy from which to cut the new gear.

Hi John ,


Thanks very much!!! That’s very encouraging. Perhaps the gear maker here will not have problems either...:)

If he does I’ll get back to you and perhaps contact the gear maker in New Zealand for his ideas.

We have also serviced the main furling gears with the original Italian parts.

Thanks again!!

Hi Helen and Kostas


My Santorin is 1991 and we had the same problem a year ago. We managed (in New Zealand) to get the worm drive machined and then a new disk gear cut. All bearings were also replaced. The cost as I recall was about NZ$2000 or roughly US $1400 which included courier charges. The fellow who did the work had never before seen a fiberglass gear box casing but reckoned the rebuilt box would be good for 25 years!


We took the furler gear box to the gear maker; no plans were necessary


I have also just replaced the gear boxes on the main furler and boom outhaul. Both about US$ 300 and standard bonfiglioli (sp?) units.

Dear all,


Our electric furling system on our Super Maramu no 29 in 1990 is broken. 

The gears inside are sheared . We had already replaced the bearings inside when it was making some noise a few years ago but this time the mechanical engineer here on Syros island in Greece says that he will need replacement gears as it will be very hard to have new ones cut and probably very expensive.

Has anyone had any experience and does anyone have any ideas to help?

Maud at Amel will send some plans which will help but any other help will be very much appreciated!!


Best regards,
