antifreeze question
 

I am considering purchasing a product from Overton's called "winter-eze". It is used to get antifreeze to circulate through the engine without having to remove any plugs or hoses. Has anyone used this before?
Also, why couldn't I just my lower unit flusher (ear muffs) with a short piece of hose to a funnel, and pour antifreeze in until it comes out with the engine running? This seems really easy, am I missing something?

PS- I would still use Sta-Bil and fog the carbs, etc.
Thanks!

The "winter-eze" is essentially what you described doing with a funnel, hose, and muffs. Thing is, I find it very easy to just drain the block, disconnect the hoses to the water pump and let them drain (then you KNOW the water is out). Then fill the hoses with antifreeze and reattach. A screwdriver is much cheaper, and it gives better peace of mind knowing you got all the water out of all locations.

I like unscrewing the freeze plugs to make sure they aren't filled with gunk, and manually filling the block with antifreeze myself. That way you don't run the risk of air locks, running out of antifreeze, etc.

I second pulling the drain plugs. You want to get the sand, and other crud out before you add the anti-freeze. Also, I want to point out that there are two different anti-freeze solutuions available. One starts protects down to -50, the other to -100. It's more expensive but if you keep the boat outside it might be well worth the extra cost.
