I am working on memory here... so it might be wrong...
I had a
Sailomat on my old boat, and my recollection is that NO grease was to be used, all the moving
parts were self-lubricating. If they were binding, a
water flush to remove
salt was the first tool. If the bearing surfaces were worn, replacement was the next option.
But, as always, read and follow the manual, not the vague recollections of an old sailor.
In general, grease in environments exposed to
salt water and air is a bad idea.
Salt water lands on it, the water evaporates, leaving salt crystals behind. It gradually collects salt crystals, and the grease gets more and more gritty and abrasive with time.
