What's the best lube for sea cocks? I heard white lithium grease is not good. Any recommendations?
 
Best insurance to have a seacock working when you really need it to is to regularly operate it. Once or twice a year is not enough.
 
When I saw the thread title some bad 70's music from a Tracy Lord's type movie came to mind.
No seriously working them as said above is the best thing to do. I don't know why a squirt of WD-40 wouldn't hurt them though.

Can one lube a seacock entirely while the boat is in the water? I am really not all that impressed with the overall maintenance design of mine. It appears I have to remove the hose attached to the seacock to get the upper half of the ball and have the boat out of the water to get the remainder. When I think back to my Haze Gray days, ships only came out of the water every 5 years, yet we had a PMCS (Preventive Maintenance Check System) to preclude them from freezing.
 
I guess I should add if it's the ball valve type with the Teflon seal you real shouldn't have to lube it.
 
Superlube.

I use the stuff for everything now. It's great for o-rings, tons of stuff. I have multiple tubes on the boat and at home. The only thing I have not tried it for is in the medicine cabinet.

The problem with WD40 is that it will wash away any grease already there and not last as long.
 
Plumber have a lubricant they use for valves but one told me some white grease will do just fine.

I can't recall for sure but thought I saw a pipe plug around where the ball valve is located. I will have to look again next time I head down, if it is there then the plug could be removed and insert grease..then plug back in.

ps I like superlube also, but that white litheum grease for cheap should be good also. I would just want to make sure it is compatible with anything it might come into contact with down stream, like impellers or ???
