You can plumb in auxiliary suctions that will let you draw glycol straight out of the jug. If you haul the boat you can stuff a tygon hose up the through hull and beer bong the glycol into the engine. Or you can try the seaflush. I have one and it works, though it might be a bit over priced. I like using the shop vac to blow the water out. That may actually be sufficient. I am cautious though and carefully consider the possibility of stagnant loops of water. So, despite "blowing out" the engine, I also run glycol. The nice thing is that I don't have to worry as much about the water diluting the glycol. It takes way less glycol to provide freeze protection.
