Unfortunately there are two tanks to empty.
Pull up the back seat. There are two access panels under there. You need to empty both tanks, doing one won't suffice.
Buy a boat bilge pump, one of the hand powered ones. They are red/white/clear. Open up the tanks then pump it by hand. It doesn't take long. Just did it.
