Duralac or something else?

I cannot think of a tiller that does not lift - If corrosion is an issue I'd be concerned Duralac, whether green (never seen it) or yellow would soon wear off.

This may be a case for constant remedial action and the only tube of Duralac not to last longer than the yacht.

It's a tiller arm. This is something that goes on a rudder stock a bit like a quadrant. Quadrants don't lift. Tiller arms don't lift. Quadrants tend only to be found on boats with cable steering and particularly monos. Tiller arms are found on boats with only hydraulic steering and frequently used on catamarans.

The tiller arm clamps onto the rudder stock with two M10 bolts then in lieu of a key uses grub screws. The tolerances in the 1/10 of mm range so there shouldn't be any movement.

Yes i've used Duralac before. Still have the stains on various items. The liquid I can think of that makes more mess is Sikaflex. Hate that stuff. ;)
 
I confess I thought you were referring to a tiller.

We have cable steering and (what you call) tiller arms, same bolts (not sure the size M8, M10) and grub screws, no quadrant. The stocks are carbon and the tiller arms, cast, aluminium.

Why not simply sleeve the stock, some form of polymer film, and isolate them from the arms

I recall that in the recent past members were extolling the virtues of a grease, instead of Duralac - the name of which I forget - I'm surprised it has not merited a mention.

Tefgel - a PFTE filled grease that isolates the mating faces it comes between.
