Anyone have any (hopefully useful) advice on how to maintain and/or
lubricate
(if needed) Marelon seacocks? Do they require lubrication like bronze
seacocks?

In reading the replies, I wondered if there is a type of water soluble
lubricant (similar to that used in marine toilets) that could be poured into
thru hull drains with valve closed. Then by opening and closing valve
several times quickly while draining, the lubricant would coat valve
internals as it passes through. May be better than nothing until the boat is
hauled.

This could apply to Marelon or Bronze valves.
