Thunder Jet builds a variety of welded aluminum boats in sizes ranging from 18' to 30' and larger. Our boats have traditionally been powered by inboard marine V8 gas engines and jet drives. In recent years the popularity of outboards and stern drives has soared. Thunder Jet boats can be equipped with diesel engines for maximum range and fuel economy. Bob's Intermountain Marine will be happy to make a recommendation of power for your new Thunder Jet but the final choice is always yours...in all aspects of your boat. Thunder Jet has the capability  to customize your new Thunder Jet to your exact specifications.
