I have a question that I would like answered. do you really need to put in any antifreeze? I know "you will be sorry" will be the next reply. I didn't get a manual when I bought my 1996 GTX 3 months ago so I don't know what it would have said. I did buy a repair manual and in the storage section it goes to great lengths to tell you to take the carbs apart drain the fuel tank and so forth, but not a word about antifreeze. in reading many threads about winterizing, hoses are pinched off to keep the antifreeze from running out. I would think the water would have run out of those hoses when you took it out of the water just like an outboard engine. does the water not run out of the block drain hose as soon as you stop the engine?
You do need to winterize. I have seen hundreds of cracked blocks in my time due to people "thinking" they would be fine. Pink antifreeze is WAY TO CHEAP not to use it..
