Mercury Marine's primary design, manufacturing and sales/service operations in Fond du Lac, Wis., were recommended for recertification to the ISO 9001 international quality systems standard.
The recertification process takes place every three years.
Mercury Marine is the only marine engine manufacturer to be 100 percent ISO 9001 certified, according to the company.
The recent audit consisted of an in-depth analysis of all aspects of the business processes by two auditors from Det Norske Veritas Certification. DNV is one of the world's largest ISO 9001 registrars and has North American headquarters in Katy, Texas.
"I would like to thank all Mercury employees for the strong showing," Mercury Marine president Mark Schwabero said in a statement. "Our dedication to the principles of continual quality improvement and customer satisfaction will help us through the current economic crisis, and will give us a position of strength both now and as the boating industry recovers."
Mercury Marine, a leading manufacturer of recreational marine propulsion engines, is a division of Brunswick Corp.
