Was indeed referring to Bonfiglioli
For the manual furler, fresh water rinse works fine for me.

I think you are referring to the Bonfiglioli Gearbox. If not, are you saying that tapping a grease nipple into the mainsail MANUAL furler is acceptable? This is the one installed above the Bonfiglioli gearbox and mating with the mainsail extrusion.
In order to grease the gearboxes, you must install grease nipples
I drilled mine, tapped in my nipples, and voila...

Hi Ken and Iris,
Thanks for the clarification. It's helpful. Also, I note that Ken from Aquarius recommended grease to lubricate the furler, but you are recommending oil. Is the choice a matter of preference or what? Thanks again for your help.
Yes, I'm referring to the manual furler that the winch handle goes in.
I don't know how you could add oil with it in place. Mine had never been serviced, and hearing about the shearing off of the foil, I wanted to remove it to check that anyway. Mine had holes that were elongated to about 15mm, so I cut it off and drilled new holes.
There was still oil in the gearbox, but only a cup or so, and it was black. After dismantling it and cleaning it up, I reassembled it and with it lying on the bench with the opening where the drive shaft goes in facing up, I poured in the oil and then finished assembling.
Hope that helps,

Hi Kent and Iris,
Thanks much for the info. I just want to confirm that when you say you serviced the manual furler you are referring to the unit at the bottom of the main sail where you insert the winch handle to manually furl or unfurl the main when the electric system has failed. If yes, were you able to lubricate the inside of the unit with the unit in place. If so, how was this accomplished? I reviewed a YouTube video from Ken on Aquarius where he explains how to completely rebuild the unit which looks reasonably challenging. So if there's a way to lube it without disassembly I'd prefer that.
Thanks for your interest.
I just serviced my manual furler for the main. It is filled with a very heavy gear oil. I found only one place (in England) that sold it by the liter, otherwise it is sold in very large quantities and is very expensive. It was shipped to me in the USA in about a week at a reasonable price. A liter is enough to service it 2-3 times.
It is Shell Oil Omala S4 WE320
After reinstalling it there was a small amount of oil on the deck the next day or two. It stopped leaking after a few days and hasn't been leaking for two weeks including furling and unfurling several times.
What specifically did you want to know?
Kent & Iris

I did find a group of messages from 2012 that address my question. But I would like to find someone who has done this recently to ask some specific questions.
