From Wikipedia - An ethanol-water solution that contains 40% ABV (alcohol by volume) will catch fire if heated to about 26 °C (79 °F) and if an ignition source is applied to it. This is called its flash point. The flash point of pure ethanol is 16.60 °C (61.88 °F), less than average room temperature.
So, once things warm back up sparks from any source (like a pump that wasn't designed to pump flammable liquids or the wallace stove), could set the water/ethanol solution on fire. |
Thanks Roger, that's a pretty significant downside I hadn't thought of. Preventing a funky flavor in the tank is not worth risking setting your boat on fire! My tank already tastes so terrible the red antifreeze would be an improvement I think. |
