My engine raw water pump will prime if I leave the seacock open for a haulout. My air conditioner will not and needs to be primed when put back in the water.

For that reason, I close the seacock to the AC prior to a haulout. I don't close the engine seacock because the marina might start the engine to move the boat if they put it back in when I'm not there.
