Does anyone use white lithium grease to lubricate their thru hulls? I was planning on using the little "straw" to shoot some grease up into the closed thru hull then open and close it several time. Any suggestions -- how do you lube yours? Thanks.

waterproof grease
Steve What you described will help but if the boat is still out of the water, you probably want to do it more thoroughly. Depending on what type sea cock, some have grease fittings you can remove for this purpose. Regardless of what type, you'd be best using a waterproof grease e.g., Lubriplate, as it will last much longer than lithium grease. If you don't have grease fittings, get access from both sides (requires removing the interior hoses or disassembly of the seacock). Having said the above, I've done it both ways depending on how easy it was to remove the hoses and find doing it correctly does make a difference. Regardless, lithium grease will wash away pretty fast.

I've good results ...
...using both tub white lithium (which may last longer than spray lithium) and Lanacote. The latter is particularly well suited for Marelon through-hulls and for bronze seacocks with stainless balls.
