Had to winterize her

[nipper]

I got them all. There are 3 on my engine. One each on the port side and starboard side block, and one out front on the starboard side (I guess that comes out of what you refer to as the J hose). I then pulled all 6 coolant hoses and filled those suckers up with antifreeze until it started coming out the back. Then I put in some more just to be safe. I always used to run the muffs hooked up to a 5 gallon plastic jug with a 50/50 antifreeze mix. I did not have good luck with that one year, and my block froze up (hence my new motor), so now I go by the Mercruiser, with the addition of the antifreeze.
