If you use a Groco ARG strainer (ARG-1250 or 1500) you can leave the thru hull open. On the ARG the outlet to the engine is lower than the inlet from the drive.

On a Bravo (no water pump in the drive like the alpha) you just unscrew the cap, toss the hose in and start the engine. All of the excess water will go out the intake and out the thru hull.
