leave in antifreeze OK?

[Mbrgr1]

I winterized (drained) my twin engines (merc 165's) but I am switching back from automotive HEI ign to points, and back to mechanical fuel pumps, I'd like to be able to run the engines during this process, but don't want to get caught in a freeze.

Are there any problems with putting a bucket under the outdrive and filling the motors with marine antifreeze and just leaving it in there so I can run them when I want to?

Thanks, MK

Are these raw water cooled engines?

i dont see why not as long as it doesnt reach its freezpoint? i could be wrong but it would make sence that would be ok. then engines will always have antifreeze in that way.

Unless u have plans on running it out of the antifreeze filled bucket for a long period of time i would think it would be fine.

You will have to do an initial drain before firing them up in the bucket or you will dilute the antifreeze, otherwise that should work.. That's a LOT of antifreeze tho

I did drain them already, and didn't get more than a gallon out of each, good question though, how many gallons each. Thanks

depending on the size of your buckets. You'll probably need 20ish gallons. 10 gallons per tub min
