if you dont slosh the boat too much i would drain the tank into a jug until you get straight fuel. you will get 90 % of it. if you slosh it too much then it will be a lot harder to get most of it out.
how big is your tank, can you drain it out into jerry cans then drain the water from the cans
My tank is 29 gallons. I dont even know how to drain the fuel out of it?! I dont see an inspection port. How would one go about draining the fuel tank?
