Mercury Marine has broken ground on a two-storey Noise, Vibration and Harshness (NVH) facility in Fond du Lac, Wisconsin. The company said that the US$10m investment will be completed by the end of the year. It will add about 20,000sq ft.

NVH is the engineering practice of studying noise, vibration and harshness characteristics. The new technical centre will contain two marine-specific, hemi-anechoic chambers, structural dynamic testing bays, listening rooms, offices and workspaces.

Tim Reid, vice president of product development and engineering, said Mercury’s investment in every new engine class includes making sure it is the world’s quietest and most reliable. “This new facility will allow us to continue to support NVH development and allow our engineers to study every noise, movement and performance indicator on every engine that enters the market,” said Reid in the statement.

Reid said that its 3.4L V6 200hp FourStroke outboard, launched in February 2018, is 15-30% quieter with 50% less vibration than the leading 200hp four-stroke competitor.

The NVH facility will be Mercury’s third major expansion in 18 months. In early 2017, Mercury opened a new US$24m EDP paint plant and in April 2017, the company commissioned a 4,500-tonne high-pressure die-cast machine, the largest in North America. Mercury has invested more than US$800m in its facilities since 2009.
