I have read a lot of post about winterizing carb motors but what about EFI models? I can't spray that water evaporator in my carbs so what steps do I take besides the following?

Change Oil
Fill engine with RV antifreeze
unplug battery
open cusions and spray with anti mold agent
I also spary my boat interior with Ortho bug spray

Anything else?
