Just making sure

I ran both engines....for at least 15 minutes. Drained the engine blocks, and the risers/manifolds. (4 total brass plugs/each engine) and then I ran them on my tank with 5 gallons of pink stuff until the tank was empty pink stuff came out of the exhaust. Good....right????!!!!! I am a bit paranoid. OH, and I sprayed about a half can of fogging oil down the carb in the middle of this process. I am working on the house water system next, but I am worried that this mega storm might sweep me right off the jack stands!

Sounds like the same system I have used forever...no freeze problems yet (knock wood).
Your good to go......and finish the rest of the boat.
