Assuming you are talking about old style Bronze seacocks, ones with a
tapered plug in it. ( Not sure the newer ones with the Ball use
grease).

1st, if they are running ruff, clean them well and use a little 'Valve
Lap' compound (auto store) and work them around a few times. This
will even up any worn areas. Skip this step if they already work
well, no hang ups, and do not leak out the sides.

Then I understand the best is any good water-proof grease, someone
said Trailer bearing grease. Key is that it does not wash out, and
that it will not create odd currents being in salt water.
