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.
