The cowl won the Conference Award, the People's Choice Award, the IDSA/Plastics News Design Award, and was also recognized as the most innovative entry in the competition's Recreation and Leisure category.

The top cowl is the largest component ever injection molded from glass reinforced nylon. Made of a 33 percent glass reinforced DuPont™ Zytel® nylon, it is shaped like a giant scoop. The rear cowl is also molded from Zytel®. The front cowl is molded from DuPont™ Minlon® mineral/glass reinforced nylon for added flatness. The lower cowling consists of two parts molded from DuPont™ Surlyn® Reflection Series® supergloss alloy for superior gloss without paint.

In addition to the cowl parts, the Verado™ engine has 15 other components made of various DuPont high-performance plastics.
