I recently winterized my 454 IO however I want to make sure I am not at risk. First I did the oil change etc. Then I drained the water from the block trough the drain plugs. (at least on one side) Next I used the bucket method to draw in antifreeze through the out drive with the strongest marine antifreeze I could get. I ran the motor for quite a while and it drew in about 4 gallons. I also pulled all the hoses off the thermostat housing and poured anti freeze into each. Lastly I fogged the engine out and closed it down. Here is my question. Due to the location and obstructions I could not get to the block drain plug on the right side (when looking aft) so I never drained that plug. Since at least one article I read said if you use the bucket method through the out drive you should be safe and some people prefer to stop there and not to drain the block I though I would be safe with everything else I did.
What is your opinion on this?
