Never gate type, always 1/4 turn somethings, barrel, ball, tapered
plug, etc, Also, always, a proper flanged base seacock with a backing
pad and ball drain, not an inline valve attached to a thruhull spud.
Conbraco, Groco, Perko, Forespar etc.

Should sea cocks (under the water line) be ball valves or gate valves?
