What grease?
« on: May 06, 2010, 03:45:01 am »
Being VERY old school (well past the sale by date) , I've always used Vaseline to pack my prop and rudder shafts but I'm trying to bring myself up to date and have been told that the 'modern' trend is to use oil  {:-{ ?!?

Could you please advise me :-
1/ What grease or oil does everyone use for packing prop shafts and rudder tubes? and
2/ if you use oil, do you need to fit rubber seals to prevent the oil leeching into the water?

Thanks, Paul

Waxoyl (usually used for rustproofing underneath of car bodies).

Just out of curiosity, what is wrong with using Vaseline anyway?

I suppose it depends on what you are suffering from. They say KY jelly is a good substitute....

As far as boats are concerned Vaseline is too stiff and saps power. Everyone seems to have their own preference in this line, no two of us seem to agree. I use motor oil on the basis that it is designed for fast moving metal to metal contact and creates no drag but as our friend FLJ says - suit yourself.

A bit too thick, my man - certainly for this particular purpose  %)

Vaseline is water based and breaks down over time i think aswell PMK.  :-))

nothing wrong with using motor grease as long as its not too thick to cause drag on the shafts.

Ah, right. So it's too thick, creates drag and it's water based.
Thanks for the heads-up.

Where can I buy Waxoyl?

What about that black grease they use for CV joints on cars.   Seems to be quite thin stuff.

  Scrape it orft a sheep, basically lanolin disolved in parraffin.

  Strange that one FLJ, cos once the parraffin starts to dry off the "Grease thickens up"?

 CV joint grease contains Molybdedendum disushics -- Black Moly -  runs quiet with that in the tube. Mix yer own similar by using Castrolese (or whatever they call it now) H/T wheel bearing grease and add Graphite.

If I played the poverty card Dave I would not shop with you  {-)

That little tube has lasted 16 boats over the last 4 years. Not bad I think.

Never mind the theory - it just works (for me and several others).

I suspect that the fact that everyone has their own favourite simply demonstrates that anything oily will work within reason. Just that if you stuff the tube with thick grease you will greatly reduce your battery life or worse.

Has anyone tried the stuff the big boys use? Or would that not be pc?

http://www.marinescene.co.uk/category/520/grease-amp;-lubricants

Is the stern tube what I've been calling the prop shaft?

At the risk of being too nerdy, doesn't the viscosity you need depend on the rpm of the shaft and the tolerance/condition/material of your bushes?

Vaseline does sound pretty eco-friendly, if it doesn't disolve too quickly



I think that's about two-penneth worth.

The stern tube is what the prop shaft runs in.
