Re: [Amel Yacht Owners] Furling Gearbox Differences

Craig, et al,

I had a slight amount of dissimilar metal corrosion between the stainless steel grease fittings and the cast aluminum gearbox housing. Using plastic/nylon/delrin screws/bolts is a good idea if you want to keep it looking good.

Sorry we missed you - have you headed south? We're in Ft Pierce for a bit.
The plastic caps/plugs are fine, although grease fittings always bathed in, er, grease, are not prime candidates for corrosion :-)

Hi Craig,
   We saw your boat at Oriental NC,  but couldn't find you before we left.  
I too was surprised that the cooling fins did not interfere with the mast.  I was prepared to grind them off,  which isn't too big of a job as it is aluminium and easy to take off metal.  

I agree with you on the zirc fittings,  if my original gears had fittings they would still be on the boat.  Bill R,  cautioned to replace fittings with plastic caps when not greasing to prevent galvanic corrosion.

hi John,

As I noted, you do have to grind the fins on the SN, Sounds like the SM mast section is a bit bigger.
And, Ian, I had to remove the boom and use a hydraulic bench press to remove the shaft from the line tender. Since it has a woodruff key I did sand it down a fraction when I reinstalled it so next time should be easier. Also, you'll want a proper drill press with long bits to drill the holes. Also, since you'll be opening the unit the factory gear oil will seep out - suggest using grease on reassembly and add Zerk fittings for periodic maintenance. I never had much luck with the paint lasting very long, but your technique sounds good, Wonder if a 2-part like Awlgrip might be more durable. I had though of having it powder coated but didn't want to remove the rubber plug and seals.
Good luck with it,
Craig SN#68

Hi All,
   I replaced both outhaul and mainsail furler bonfig  gearboxes and did not have to grind down either one.  Both were bolt on replacement.

Just about to fit 2 new Bonfiglios. Grinding one
down to fit was easy as it is aluminium or something very
similar. Then you need to paint it. I used an aluminium
etching primer and the two or three one part top coats.

Not anticipating an easy job with the Anderson separation,
but I’ve got everyone’s notes to hand!
