I chickened out, went to the parts store to get marine antifreeze and there was a boat mechanic there, It was meant to be I took it to him. He told me he will get it up to temp using water and make sure that the thermostat is open and then pipe in 5 gallons antifreeze. Then he will pull all plugs and leave them out. Pull spark plugs and spray in some seafoam or something, turn it over a few times reinstall spark plugs and she will be ready to hibernate.
