Hello everyone,<br /><br />I just started my Johnson 1981 60HP outboard. The temperature outside has been above 50 degrees even at night. <br /><br />I had RV antifreeze in the system before I started it for the first time this season.<br /><br />Now I find out that tonight it will be 33 F. The rest of the week says it will be be 47 F or above. This crazy May weather 
<br /><br />Should I go over and put the RV antifreeze back in the water system? <br /><br />Will one night of 33 degree weather hurt any of the seals? <br /><br />The engine was drained of all of the water when I pulled it from the lake, but I know there is some still in there. I don't want it to crystalize and blow any of the seals.<br /><br />Any information would be greatly appreicated.<br /><br />Thanks in advance!<br /><br />Shade
