A calcium based greases are among the more water resistant offerings. At low speed and medium pressure calcium sulphonate is a good choice.
I contacted Shell and one of their product specialists called me back. After a discussion of the properties of marine winches she recommended looking at the Shell SRS 2000 line ( now renamed Gadus I think ). I got the Extreme version which is calcium suphonate based, $12 for a standard sized grease gun tube. I would expect it to be a lifetime supply. After two years the grease is holding up better than anything I have previously tried, which includes the Lewmar/Harken greases. Previously I would rebuild the primary winches every year and have a mid season tear down to check and maybe add some grease. I took the winches apart after a season and it looked good, better than they usually would look mid season. There is information on the web if you are interested. Note it is a specific version.

The Lewmar grease seems expensive and I?d have to order it.? Chris?
