The problem with the grease on the roller bearings is not caused by the quality of the lubricant but by the evil combination of salt and heat which over time sends the lubricant dry and crumbly. If you could arrange to do all your sailing in Finland the winch grease would last years longer because it is not very hot and the water is not very salty.

The most durable winch grease I know of is Super Lube. It will give you two years on your primaries and four or five years on the halyard winches, assuming you use furlers. It can be used for longer but the needles will incur salt damage.
Let me start by saying in my former life as a chemical engineer I formulated engine coolants and lube, including several patents that are in active use. I also did a lot of testing in the process of developing additive packages. This is near to my heart.

I believe you have great experience, but experience prior to about 2005 is not relevant; the better products did not exist.

Heat and salt will not make a quality synthetic turn dry and crumbly in 5 years. In 5 years, they will typically look new. They do NOT oxidize at temperatures below oven temperatures. It would take 15-20 years for the environment alone to damage the grease. Dirt is a separate matter.

As I said earlier in the thread, Superlube is a good product, but it is not impressive in saltwater service. Green Grease (Omni Lubes), Lewmar Winch Grease, and many other synthetics are much better in terms of wash off and corrosion protection. Thus, it is not a valid data point. BTW, not all synthetics are formulated for saltwater; I listed two that are well tested.

Thus, we do not know that there is "no such product." Perhaps we haven't really looked for it in a systematic way.

---

I wouldn't use lithium grease; it is not the most stable. But I do believe a thin coating of a high performing synthetic may be an option worth investigating. All of the cases of stuck pawls seem to involve very long service with too much cheap grease. A good grease could not cause the problem.

But too much of a bad grease, ignored too long, certainly can. Absolutely. I've dug through old winches and old machines. And that is a pretty darn good reason for the winch guys to say "no grease." I'm not planning to investigate grease for this reason.

Interesting, but I didn't see a US source. Where did you get it?

This is heavy grease; not for pawls.

But while I'm at it, what else would be worth testing?
  • Passenger car motor oil, if only to confirm it washes off too fast.
  • Several bicycle chain oils.
  • Chain saw bar oil.
  • Lower unit oil. This is too thick (manufacturers generally spec 100-150 ISO), but I'm curious just as a comparison point.
  • Other?
I'm open to suggestions. The problem, as I see it, is that manufacturers recommend servicing winches 1-5 times per season, which just sn't going to happen for most people. Modern greases can easily go 5 years, for most people, but the oil can't, and as a result, the pawls and their seats go first. Certainly there must be modern lubricants capable of longer intervals?

T9

You don't want anything too tacky or grease as it can cause the springs to stick and the pawls not engage

Re: Testing Pawl Oil For Winches

Andersen recommends using the same grease (theirs) on the pawls and springs as the rest of the winch. At least this was the case at the time my winches were made (c. 2000).Not sure if this is still the case.

I've never had the pawls stick, although one did when new until I cleaned and lubed w/ winch grease.

I last used lithium grease, but will reconsider now. Will be interested in what your test reveals. I have some lube made for an M-16, but I suspect it is lithium.

It is actually not a heavy grease at all.....thick semi liquid in jar.
The name is kind of misleading.....

Google liquid o ring 101 as is available many places....

Also source http://marine-outfitters.com/catalog/item/liquid-o-ring[emoji768]-film-forming-lubricant
Really useful for many applications on boat...then we had to get jar for the garage, then the aircraft hangar....
Great to not have a single purpose product on boat....husband had it out today as he was rebuilding water maker pump........

Re: Testing Pawl Oil For Winches

3 n 1 pawls
Lewmar grease on bearings and gears

I don't think T9 would work on pawls, dries to a protective waxy film. It is good stuff.

a. I have tested Anderson grease (oxidation, wash-off, corrosion, EP) and it is a nice product.

b. I've actually used a thin film of grease. Always worked perfectly. Just didn't want to admit it in front of such a stiff crowd. Figured I'd get to that later.

c. Anderson Winches. Grease for pawls. bearings, and gears. (page 5)
https://drive.google.com/file/d/0B5-...I0bnMwTzg/view

11. ... Pawls should only be lubricated with a very thin film of Anderson Winch Grease.

It is a long-lasting synthetic that overcomes the problems we seem worried about. I had not read the Anderson manuals, because I have always had Harken and Lewmar winches. They also list the service interval as 2 years.

d. Antal. again, grease is recommended on the pawls (page 1).

Maintenance Winch

When greasing a winch, apply using a brush on all moving parts including pawls, gears, spindles, shaft bearing washers, etc. Regular cleaning of the winch will improve it's performance and longevity. For winch and gear lubrication, use Type 400 (green) with Teflon.

-----

So that makes it 50/50. Half of the vendors say high quality grease, half say oil. Since that is hardly unanimous, I guess I'll make some calls.

Re: Testing Pawl Oil For Winches

We have had success with synthetic greases. Most standard greases and oils are comprised of mixtures of different molecular weight oils that are blended to achieve a desired viscosity. Over time the lower molecular weight oils evaporate or wash away, leaving a thick sometimes varnish like residue. Synthetic oils and greases tend to have a narrower molecular weight or length that inherently has the desired viscosity w/o blending. There is less tendency for lighter components to evaporate. We clean our winches every 1-5 years and find that the synthetic greases show no sign of degradation. We clean and replace the grease anyway. Cleaning away the old grease is a snap.

We keep the boat on the hard for about 7 months each year. Most boat yards are dusty places. Each year before we leave, we tie ropes around the base of the winches and knot the rope with a simple square knot. This helps reduce the amount of dust that gets into the winch. Surprisingly, the ropes were still there after Irma and Maria.

Re: Testing Pawl Oil For Winches

For pure longevity I wonder if just rubbing them with a little pure carnuba like Harley wax or Mother's wouldn't last forever.
Long ago for bicycle racers for the daily work out bikes ridden in all kinds of weather we'd soak a clean chain in melted paraffin.

It's not chainsaw chain oil it's just chain oil.

Re: Testing Pawl Oil For Winches

Pawl oil? Is this some real spendy 'yatchy' stuff like a gotta have fishing lure that lures the fisherman to lay a wad out, but fish could care less about? Sounds a bit like 'radiator lube' or 'prop polish'.
