Re: Closing seacocks
I closed all primary seacocks only when I leave the sailboat for a few days or so. (Engine intake, head, sinks, etc..). I am not concern with the seacock as much as a hose or clamp. My bilge pumps wouldn't have chance.
Early last year the Marina moved our previous sailboat, Pearson 35 and never open the engine seacock, and burned up the impeller. They indicated that everyone in the slips leaves their engine intake seacocks open. They made me think that I was paranoid... but I still closed them.
