Sorry to hear, not the end of the world though. Do what they said, rinse everything really well and apply lubricant to all electrical connections. Would get rid of all the fuel and flush the tank. Run the engine off a small auxillary tank to get it going again. If you can get to the gash from the inside I'd go that route, regular epoxy resin with some mat and cloth. Some glass on the outside as well to fill in, or some marine tex, sand and touch up paint.
