"and it is the first time in the water this season, the seacock may be closed " A tirck to learn from aviation ground crew: They put long red streamers on things (like intake covers) that must be removed before startup.
A good way to make sure the raw water intake is open, is to tie the ignition key to the intake valve handle with a red streamer or yarn. You may spend a few minutes asking yourself "Where'd I leave the damn key?!" but you won't start up with the intake closed.
