Re: New gearboxes - painted or bare alloy?

I agree with Ian about removing the outhaul gearbox shaft regularly to keep it free.  However, I recommend once a year minimum.  I had to replace the outhaul gearbox after two years of ocean sailing and it was completely frozen.  I hired a local Amel specialist and it took us 6 hours to get it off.  We tried 3 different pullers and eventually had to use a grinder to cut the gearbox into small pieces.  Not a fun project.  I greased the shaft heavily.  There's no need to remove the gearbox completely, just remove the shaft which is held by a single nut and regrease it.  Should be 20 minute job.

Mike,
You may have to grind the fins off the mainsail furling gearbox to fit in the mast profile. So you’d need to paint over anyway.
I changed mine three years ago. I painted with an aluminium primer and top coated with a one pot paint that matched the mast/boom.  It’s worked fine, and if it gets scruffy I can paint it again.
I would say that one of the gearboxes was filled with oil, the other with grease (there was a discussion on this) The oil dripped out (in small amounts) of the seal onto the deck,  so I refilled it with grease instead. Don’t know when you last removed the boom gearbox, but I take mine off every two years now to keep the outhaul shaft easy to free.
