I found that the K99 in my remote greaser had separated, oil above the plunger & a solid mass on the pressure side.
The solid mass had to be purged by removing the stern tube end & coiling the nylon hose in hot water with the plunger pressure applied.
I have changed to Keenol, twice the price & time will tell.

Keenol ?

Surely that has not been available for years ? Ramonol white grease usually suggested as the alternative.
 
Something wrong with the greaser if the oil has got above the plunger?
the seal seem to be tight enough & i applied great pressure to force the thick grease fillers out of the pipe, in fact i used mole grips on the handle & split the nylon hoes just below the greaser housing. This is when the boiling water came into play. nothing above the plunger at that time
 
Is there a particular reason why one would use water-resistant white grease rather than water-proof brown calcium grease for this application?

It seems the reason might be because it is more visible. ?????

OK .... that's surprised me a bit but I don't doubt your research.

Just wondered because I've just removed the remaining white marine grease from my rudder bearings and replaced it with the waterproof calcium grease which I think you told me about. I've still kept the tin of white grease on the boat and may well continue to use it on stuff that is not in contact with water but otherwise I've switched to the brown.

I use Morris Oils K99 grease for every greasy application on boats. I know there are better products for some particular applications but don't consider it worthwhile to carry several different cans. Morris Oils K99 grease is a good all-rounder and I've used it on sternglands without the problem described.
