Ok....I disconnected the Vro and drained my tank. But...there maybe a couple of gallons in the tank that don't come out. Since I'm gonna fill the tank...should I mix the first time 40:1 because I don't know how much fuel was left in there? Or maybe go like 45:1. The tank is under/in the hull so other than the needle showing empty...I'm really not sure. I've practically exhausted my hand priming the bulb trying to get every last drop out ,but there is some left. <br />Also....how do you guys start the engine when the boat is been sitting for a week at home. Do you guys use a portable tank or once it's mixed...it's ok to start it up after a week just sitting there?
