Re: I/O VS Outboard
Well, sorta...don't forget the cost of the fogging oil...so less than $10.
That's what I spent to winterie my I/O... plus a small amount of antifreeze.
I used to hook a 6' hose to the muffs and put 'em on the drive. I had a big funnel stuck in the end of the hose. I put half of a gallon of antifreeze in an empty antifreeze jug that I had and filled 'em both with water to give two gallons of 50-50 mix. I'd fill the hose and funnel with the mixture and crank and run the engine while continually filling the funnel. I did this until the antifreeze came out of the exhaust. Granted, I live in NC where it's not all that cold. We do have a few cold days and nights a year when it's down in the 20's. The boat was stored on the north side of a shed in the shade, so it really never got warm on those days. Besides preventing freezing, antifreeze is a rust inhibitor, which has got to be good for those manifolds and risers. It wasn't much trouble to do this, but I don't know that I'd want to do it more than once a winter if I used the boat during cold weather!
Another plus, to me, is that the single carb. on an I/O is a lot cheaper to rebuild or replace than the multiple carbs on most outboards. That old Holley 2-bbl was easy to drain and seemed to be a bit more tolerant to ethanol and moisture in fuel. I don't know if this experience is universal or not.
