The Dry Weight is 397 lbs. With a full tank it will vary based on the temp, ie the typical weight of gasoline at 72 degrees F is around 6.25 pounds per gallon. As it becomes cooler it will be more dense and thus weigh more and above this temperature it is less dense and a gallon weighs less. So at 72 degrees with a full tank you are looking at about 20 pounds.
