for refilling stern gland reservoir. ok its easy to spoon in, but messy. i can easily get LM grease at local industrial supplies shop, but they were unsure about marine grease in this form etc.

Ramanol Advanced
Castrol BioTac EP2

I use IGOL waterproof grease too, as I have a large tube of it from previous years.:D
 
thanks.

but its the marine grease in a gun cartridge i'm looking for. to avoid the mess, and air trapped within reservoir when you fil it from the top etc.
 
I greased my stern gland for something like 12 years with bog standard Castrol automotive grease, lithium based. Perfectly OK, and comes in a cartridge. Replaced the packed gland with a PSS seal, mainly to avoid the hassle of greasing.
 
You may find, as I did, that the greaser unscrews from the bottom so you can wind the plunger right up and fill it from the bottom. Tins of waterproof grease often have a plate on the top with a hole in it so you just press the greaser on it and it fills up.:)
 
I used to remove the greaser as described by MoodySabre and spoon the grease in with the plunger fully withdrawn. That way I was able to minimise any air bubbles and never had a problem. I used Keenol grease purchased from chandlers which seemed fine and not too expensive. I see that Mailspeed and Force 4 sell Ramonol grease as a substitute for under a tenner.

ok will hunt for some standard Li grease then! was idly checking the temp of the stern gland on a long motor, it was about 65 deg, and stayed pretty constant. never checked it before. but possibly too hot for bog standard LM grease i think.

interestingly the grease reservoir looks as tho the base should unscrew, but i couldn't unscrew it last time, so thought it must be decorative to match the other end (old brass thing) but will try and give it more welly next time its off. cheers for that idea.

edit been looking at LM grease, i always thought it stod for Low Melting point, but from what castrol are saying higher than anything the stern gland should get to. hopefully! "Lithium based, high melting point grease, specifically designed as a wheel bearing grease for use over a wide range of temperatures"

The Morris waterproof grease seems as good as the others to me. The way I fill my greaser is to unscrew it from the base and wind the handle up. put three or four large spoonfuls of grease in a plastic food bag, roll the grease into a sausage shape small enough to fit into the greaser, cut the end off the bag, pop the bag into the greaser, then holding the greaser and the bag tightly, pull the bag through your fingers leaving all the grease in the greaser. No mess.
 
I used a tin of Unipart waterproof grease I found at Preston Marina chandlers, it was cheap IIRC. It says it's for trailer wheel bearings and stern glands so, so long as it does what it says on the tin it should be OK.

Mine looks like this:

The top does come off but it left the plunger behind. The base was reluctant to move so it had a couple of applications of WD40, then it came off. I wound out the screwed plunger shaft and pushed the leather washer back down the barrel then scooped up a bit of grease. Then I had to tap the greaser firmly on a solid surface to get the grease to drop down the barrel. Half a dozen repeats of this and the barrel was full enough to refit.

The grease seems less viscous than what was in before so it's easier to put ½ a turn on, but it all seems OK for now.
 
"waterproof grease"

people keep mentioning "waterproof grease". Does anyone know of a grease used in machinery that is not waterproof? is there one that is water soluble?
