Forward Air is by far the cheapest shipping/freight company I have used (
www.forwardair.com). They have shipping terminals all over the country. If you can get the motor dropped off at one of their terminals, and pick it up at one, you will save a ton of money! Just call them (800-726-6654) with the pick-up and destination zip-codes, and they can look up the closest terminals at each end. They should also be able to give you a quote if you have the dims and weight.
