I also pulled my thermostat and just poured in a cup or two of regular anti-freeze coolant as a precaution. Be sure to start up in spring in your driveway so the coolant doesn't get into any lakes.

Pull out your impellar too. Leave hoses off to dry out.

Drive boat around with hoses off to get any excess water sloshed out. Drive up and down hills, left and right turns. Just gives you a little piece of mind.

I think you are pretty close though....
I drained all water before sucking up RV. I pulled both petcock and knock sensor out along with draining all hoses including impeller. I probably could have left it as is.

I might uptake another 3 gal next time I go up to get it into the mufflers.
