I wondered the same thing about the engine cooling down and the thermostat closing. I just repeated it all today again: running up to temp, draining the block and risers, adding 6 gallons of AF to the bucket, running until the AF was sucked up and fogging at the end. The time between shutting the engine down at 140 degrees, draining and starting up again was about 5 minutes and I hope to heck that wasn't enough time for the T-stat to close - I doubt it with all the mass of iron heated up. The boat is now in storage but easily reached so if this niggles at me I will go up and check the block/risers/t-stat hoses just to make sure there is AF in there. Steep learning curve as with all things new. Hopefully not so steep that I end up with something cracked.
