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.
My Marina, will not start engines on vessels unless they have been issued a work order to commission the engine. They gondolier boats to and from the slip otherwise. They are quite good at it.
I imagine that they've heard the, " It was working fine when I left it" line enough times that they have taken this approach.
