Hi, I am new to this forum and am looking forward to learning all I can and making new friends.<br /> My question is this: I have about 20 outbards that I am restoring right now but it is winter and I am trying to figure out how to run my motors in a tank but can't afford to keep my shop heated all the time. <br />I am thinking of just putting anti-freeze in the water so it won't freeze. Will this hurt any of the seals or impellers? <br />Thanks in advance<br />Joe
