I'm not sure if it's true with boats or not but the term "Dry Weight" for many motorized devices is total weight less fluids (fuels/oils/etc) and that may be the same in that case. They may have included the base engine in that which was probably around 350-400 pounds at the time. The few older SC and other boat brochures I've seen (and some new stuff) usually indicate hull weight or weight no engines...
