It happens to my ship all the time.
Take the hose off the engine side of your seawater pump, and let the water squirt in, then shut the seacock again.
Reconnect the hose and you'll be fine.... well, it works for me, anyway.
It will run fine until you lift the boat out again.... it sound like that is ofetn, if you have a trailer sailer.
