That's good advice, as the graphite is highly conductive and could increase galvanic action between aluminum and whatever more noble materials are in contact with it. Frank Brown, who was a well known Merc mechanic that used to crew for Carl Moesly on the race boats, used a mixture of anti-corrosion grease and Never-Seize on prop shafts and I've had good luck with that, but the mating parts are steel and brass/bronze, so no aluminum is involved. I normally use anti-corrosion grease on bolts, but Tef-gel would be a good choice for SS & aluminum combinations.
