Mistake made winterizing a 5.7 liter merc

[Chet labrozzi]

Ok guys, here is my problem..I didn't drain the block correctly, didn't remove the two lower drain plugs one on each side prior to starting and running rv antifreeze through the system via muffs on the lower drive. After doing some research on here, and alot of help through the forum. I located those drain plugs, opened one up and caught a fair amount of fluid. It's pink however it's not as pink as the new straight stuff, I will buy a tester and test it, here is my question, if it's not high enough against freezing, can I just remove the 4 plugs and refill through the hoses? Will this fill the block and the exhaust or do i need to redo the entire thing via muff's?

This is not an engine forum, your other winterizing posts were moved to the Mercruiser IO forum. Please use it when you are wanting help on your engine and drive.
Next, do not make multiple posts on the same subject. If you have a thread on winterizing in the IO forum, reply to it, don't start a new thread in a different forum.
