I just finished spraying the Bombardier Engine tuner into my 1977 Evinrude 85hp. Smoked up a storm....and It was quite an experience using those "muffs". Water was flowing all around my lower unit when I turned the water on....I'm scared that I blew out some kinds of seals or something in the lower unit.<br /><br />Anyway....Can I leave the engine over night and return tomorrow (about 24 hours) to start it up to blow out the remnants of the tuner/carbon?<br /><br />Thanks,<br /><br />Joe
