Mainsail drive replacement.


Morning Ian

Below are the details of what I put in to my Santorin 

The same gearbox goes in the mast and on the boom out haul

We had a second issue recently but found the aluminium peg that links the in mast foil to the gearbox had snapped so had a new one made by a local engineer from a hi tensile aluminium 

The gear boxes have worked fine and were sourced from bonfigilioli in Auckland

Hi John,


We can offer the following gearbox to suit.


1 x VF44P 70:1 P63 B14 B3                             $325.90 net + GST.

This is usually supplied as a raw aluminium finish however we can paint it using a two pot epoxy if you’d like. Allow an extra $45 + GST for this and 1 – 2 days for the paint to fully cure.  

Parts available ex stock NZ.  


For the DC motor, we’d need to know power, voltage and speed in order to offer a replacement.


Prices exclude GST and freight.


Please see attached dimensional info for reference.


Kind regards

Photos are attached. 4.jpg has the best picture of the gear box.


Let me know if you need more


The part number came from a fellow in Europe who has the same gearbox on his boat and he says he got a gear box with that part number from the UK

Hi John,


Thanks for your enquiry regarding a replacement Bonfiglioli worm drive. If you can please provide photos of the gearbox as well as any motor details available I’ll have a look into what we can offer.
